Welcome to “Can My Dog Eat That?,” our new series that answers some obvious (and not-so-obvious) questions about what your dog can and can’t safely eat. Read on!

A grape or two might seem like a harmless snack for your dog. After all, it’s just fruit, and mostly water at that. But what happens if your dog eats grapes? Unlike other fruits like cranberries or blueberries, grapes can be toxic to dogs, potentially leading to acute kidney failure and even death. Grape and raisin poisoning are real dangers for dogs.

This applies to all types of grapes, whether they’re red, green, seeded or seedless, organic or grown conventionally. But fresh grapes aren’t the only problem. Grapes that have been dried — otherwise known as raisins, sultanas (light brown, seedless raisins) and Zante currents — can be problematic as well.

The same goes for foods in your pantry that contain raisins, including cookies, bars and breads, granola mix, trail mix and raisin bran cereal. It’s not clear if grape jelly, grape juice or wine could be hazardous, but why take the risk?

What makes even a few grapes toxic?

Until recently, no one knew why, exactly, dogs and grapes shouldn’t mix. But veterinarians at the ASPCA Animal Poison Control Center discovered that tartaric acid (the ingredient cream of tartar is made from) might be the culprit. The amount of tartaric acid in grapes can vary depending on the type of grape, the degree of ripeness and the growing conditions.

In addition to varying levels within the grapes, dogs can have individual responses to the fruit, making it frustratingly difficult to determine how many will be a problem. Dogs have had a toxic reaction after eating as little as 0.32 ounces of grapes and 0.05 ounces of raisins per pound of body weight. It’s not a food you want your dog eating!

If your dog has eaten grapes or raisins, call your veterinarian or the closest veterinary emergency clinic immediately.

Symptoms when dogs eat grapes

It doesn’t take long for signs of toxicity to appear. Within hours of eating grapes or raisins, dogs may vomit and refuse to eat. If your dog surfed your countertop without your knowledge, you may find the telltale signs of grapes in the vomit. The dog may also have diarrhea, show signs of abdominal pain, drooling, dehydration and lethargy. They may drink and urinate more than normal, or in more advanced cases, they may produce little or no urine.

Seek veterinary help immediately

Since kidney damage can happen quickly, it’s best to call your veterinarian as soon as possible. While there’s no specific test to determine if your dog is experiencing grape toxicity, it’s generally diagnosed based on the history of grape consumption or grapes found in the vomit.

When your dog eats grapes or raisins within the last hour or two and hasn’t vomited yet, the doctor will probably recommend that vomiting be induced to get the toxins out of the stomach. Once that’s accomplished, your dog may be given activated charcoal by mouth, which may help prevent further absorption of toxins into your dog’s system.

In cases of grape or raisin toxicity, some dogs may need aggressive therapy, including hospitalization and intravenous fluids. The veterinarian may recommend blood work and urinalyses to monitor kidney function. Dogs may also benefit from stomach protectants, medications to control vomiting and nutritional support.

While ingestion of grapes should always be avoided in dogs, other fruits can be healthy and safe snacks for your pooch. Consider offering apple slices (remove the seeds), cantaloupe, blueberries, strawberries or bananas instead.

Can One Grape Kill a Dog?

Can one grape kill a dog? Yes, one grape can be extremely harmful. Grape toxicity is a real threat no matter how many grapes a dog eats. When dogs eat grapes, grape poisoning is always a possibility. Grapes or raisins, quite simply, are toxic to dogs, whether it’s one grape, green grapes, seedless grapes, red grapes, etc. If you suspect that grape poisoning has occurred and you cannot seek immediate treatment, you can call  Pet Poison Helpline at 855-764-7661 for immediate advice. Your dog’s health, and kidney failure specifically, is always a concern when your dog ate a grape.

Can Nutrition Influence Your Dog’s Behavior?

If, as they say, “you are what you eat,” dietary ingredients could impact a dog’s health. Since our health affects how we feel, it seems logical that it could also affect how we act. But is there any evidence of a connection between dog food and behavior in dogs?

Dog Food Nutrition Needs to Be Balanced

Certainly, a poor diet can alter a dog’s normal behavior. Diets that are deficient in essential nutrients can lead to serious health issues, including anemia and brittle bones. If a dog isn’t feeling well because they’re weak or feeling pain, that can certainly impact their behavior.

That’s why one of the most important parts of any dog food label is the nutritional adequacy statement that indicates the pet food is “nutritionally complete and balanced” for your dog’s particular life stage. Commercial foods that list the nutritional adequacy statement have met the guidelines established by the Association of American Feed Control Officials (AAFCO). 

Because the nutrient requirements (protein, essential amino acids, fat, vitamins and minerals) of dogs change over their lifetime, there are three nutritional adequacy statements that can be found on a dog food label depending on the diet: growth and reproduction, adult maintenance and all life stages. Diets that are designed for all life stages meet the nutritional requirements for both the growth and reproduction stage as well as adult maintenance stage. So make sure you consider your dog’s life stage when choosing their diet. A healthy dog is generally a happy dog! 

Yet even a healthy diet can become unbalanced if treats or table scraps make up more than 10 percent of the dog’s daily calories. Similarly, if you’re not following the feeding directions on the label, imbalances can occur. And unless homemade diets are prepared under the guidance of a veterinary nutritionist, it can be easy for dietary deficiencies to occur.

Does Raw Meat Make Dogs Aggressive?

It has been suggested that higher dietary protein may be associated with canine aggression. That’s why some recommend a low-protein diet for an adult dog with aggression problems. However, studies testing this concept have been flawed and results were conflicting, so more research is needed.

The theory behind the low-protein diet revolves around tryptophan, an amino acid involved in the production of serotonin, the neurochemical purported to create a calming effect. Tryptophan competes with other amino acids (which are components of protein) to cross the barrier into the brain. With less protein in the diet, it’s surmised there will be a greater chance for tryptophan, and eventually serotonin, to enter the brain, thereby promoting calm while reducing aggression.

Regardless, healthy adult dogs need at least 4.5 grams of protein per 100 calories of food, so there needs to be a minimum amount of protein provided.

Pet Food Nutrition and the Aging Canine Brain

Current research does support the positive effects of nutrition on brain aging.

Older dogs can experience cognitive dysfunction syndrome (CDS), which has been likened to human Alzheimer’s disease. Affected dogs may appear disoriented, interact less with family, lose house training and show changes in sleep/wake cycles, such as wandering around the house at night.

Several factors are thought to contribute to brain aging and cognitive decline in dogs, including chronic oxidative stress, reduced brain glucose metabolism and low-grade inflammation.

Some evidence has been found recently that certain ingredients, typically added to the diet or given in supplement form, may help improve clinical signs and slow cognitive decline in older dogs.

For example, antioxidants such as vitamins E and C in your dog’s diet may help neutralize the damaging effects of free radicals on cells, thereby protecting the brain from oxidative stress. These ingredients may have anti-inflammatory effects, as well.

To counter the effects of reduced cerebral glucose metabolism, medium-chain triglycerides in the diet can be converted to ketone bodies, providing the brain with an alternative energy source to glucose. In one study, dogs that were fed diets supplemented with medium-chain triglycerides performed better on cognitive tests than dogs fed the control diet.

How to Make Your Dog Happy

While good nutrition may have positive effects on canine behavior, many problems need a combination of therapies, including behavioral modification or training, environmental management and possibly medications. If you have questions about canine behavior and nutrition and how they may affect your dog’s life, your veterinary clinic is the best place to start.

Why Are Grapes Bad for Dogs?

Among the many foods that are on the no-no list for dogs are grapes and their relatives: raisins, sultanas and currants. Dogs should not eat grapes or any grape-based foods because they can cause severe kidney failure and even death. So what makes grapes so bad that even a single grape can cause health issues for dogs?

Are Grapes Acidic? Is That the Problem?

Grapes do have a pH on the lower side so they are acidic, but the issue with dogs eating grapes isn’t because they’re acidic. It’s likely due to one particular acid — tartaric acid. If that sounds familiar to all the bakers out there, it’s probably because you’ve used cream of tartar, which is made from tartaric acid, in your baking. Unlike people and some animals, dogs are especially sensitive to tartaric acid.

What Happens If a Dog Eats a Grape?

For a long time, no one knew exactly what made grapes toxic to dogs. The type of grape didn’t matter; dogs showed signs of vomiting, diarrhea, lethargy, lack of appetite, and later increased thirst and urination, whether the grapes were green or red, seeded or seedless grapes, fresh grapes or dried (raisins, sultanas and currants). And sometimes grape and raisin toxicity led to acute kidney failure or worse.

Then the connection between grapes and dogs exposed to cream of tartar and tamarinds was made. The ASPCA explains that the clinical signs, lab results and kidney lesions seen in the dogs exposed to cream of tartar and tamarind resembled those of dogs who ate grapes and raisins. This helped investigators realize that a common factor — tartaric acid — was the toxic substance behind the kidney problems.

What Are the Symptoms After a Dog Eats Grapes?

The symptoms of grape or raisin toxicity can vary among dogs, among grapes, and by how many grapes the dog ate. A dog’s health can be affected within hours of grape ingestion; typically dogs with grape poisoning vomit, have diarrhea, don’t want to eat, drool and just want to laze around. You may notice them drinking and urinating more. If kidney damage has already started, urine production may decrease (there may be little or no urine coming out).

Can Dogs Have Green Grapes? Can Dogs Have Red Grapes?

Red, green, purple, black or yellow; it doesn’t matter what color the grapes are, don’t let your dog eat them, as they can all potentially cause grape toxicity. They also shouldn’t eat dried grapes, like raisins, sultanas and currants, since these may also be toxic to dogs.

What to Do If Dogs Eat Grapes

If you know or suspect your dog ate a grape, you should immediately call your veterinarian. If your dog ate grapes or raisins (or any grape-based food) while your vet clinic is closed, call an after-hours emergency veterinary clinic, the ASPCA Animal Poison Control Center (1-888-426-4435) or the Pet Poison Helpline (1-855-764-7661) for advice on what to do. Do not try to induce vomiting unless a veterinarian has advised you to do so.

My Dog Ate Grapes but Seems Fine

If your dog eats raisins, grapes or any other grape-containing food, call your vet. Even if your dog isn’t showing signs of grape poisoning, you should still call your vet. If it’s been less than an hour or two, your vet may induce vomiting so the toxins (grapes or raisins) are removed from your dog’s stomach. Further treatment may still be required, though.

Sensitivity to grapes can vary among dogs, so it’s best to be safe and have your dog examined by your vet if they have ingested grapes or raisins — even if they seem fine or ate just one grape.

Can Dogs Have Wine?

Nope. Any alcohol is bad for dogs. Along with grape poisoning from the wine (it contains tartaric acid), dogs can experience ethanol poisoning, which leads to trouble breathing and seizures. So make sure you keep wine glasses and bottles well out of the reach of curious canines.

Can Dogs Have Grape Juice?

Another nope. Grape juice can also cause grape toxicity so don’t let your dog sneak a sip from your glass. Eating grapes, drinking liquids made from grapes and eating dried grape products can all cause toxicity in dogs and are all big no-nos.

The bottom line is that dog owners should never feed their dog grapes or any food with a grape-based ingredient in it (e.g., raisin bread is out). If your dog does eat grapes, call your vet immediately. If you would like to feed your dog some fruit, there are plenty of safe alternatives like plain cranberries, pineapple and blueberries.

What Is the Best Protein for Dogs?

All dogs need protein in their diet, but the meat- and protein-related claims made on dog food packaging can be confusing. And, in reality, few ingredients used in pet food provide only one type of nutrient. We’ll review what you really need to know about protein and its various sources in dog food.

The Importance of Dietary Protein for Dogs

Let’s start with some dog nutrition basics and why protein is necessary in dog food. Dietary protein is really all about amino acids. Many animal nutritionists will tell you that dogs don’t have a protein requirement; they have a requirement for amino acids in the proper amounts and ratios. Of the 20 or so amino acids, 10 are considered essential for dogs — that means they must be provided in the diet because dogs can’t produce them in their body or can’t make enough of them.

The primary function of protein is to provide essential and nonessential amino acids for muscle development and repair, enzymes, key hormones (like insulin) and antibodies. Proteins are the primary structural parts of muscles, cartilage, tendons, ligaments, skin and hair. Proteins from food are also the body’s primary source of nitrogen, which is critical for making nonessential amino acids, nucleic acids of DNA and RNA, and certain neurotransmitters. Finally, amino acids from protein can be converted into glucose and other energy forms for the body to use to maintain itself and during growth, gestation and lactation. That’s a lot of important functions!

Here’s something to keep in mind: Once a food or ingredient is digested and its nutrients are absorbed through the lining of the small intestine, the original source of the nutrients no longer matters. In the case of amino acids, your dog’s body doesn’t care where the amino acids come from for its use — whether they’re made by the body or supplied in the diet as single amino acids or as intact proteins.

Protein Sources Add Flavor to a Dog’s Diet

Protein sources in dog food also provide flavor. When protein sources are cooked along with fats and carbohydrates, different flavors can be created. Animal nutritionists agree that as the protein content of food increases, the food generally becomes more palatable and acceptable to dogs.

Protein Ingredients That Dog Food Is Made From

Pet food manufacturers can use many different ingredients to supply the protein and amino acids found in dog foods. Essentially, protein ingredients can be grouped into one of three categories:

  • Animal-based ingredients
  • Plant-based ingredients
  • Amino acid supplements

Several protein sources are often combined in pet foods to improve the overall quality and amino acid profile of the finished diet. This practice is known as protein complementation, and it’s used because different protein ingredients contain different amounts of essential and nonessential amino acids. That’s why it’s common to see dog foods with one or more animal proteins, plant proteins and amino acid supplements.

Typical pet food ingredients with high-protein concentrations are meat, meat meal, meat broth, eggs and fish. Taste of the Wild dog food recipes use a variety of different animal proteins, including:

  • Beef
  • Bison
  • Chicken
  • Duck
  • Eggs
  • Fish
  • Lamb
  • Pork
  • Quail
  • Salmon
  • Trout
  • Turkey
  • Venison
  • Water buffalo
  • Wild boar

Animal-based ingredients aren’t the only protein source for pet foods. Plant-based ingredients — such as ancient grains (like quinoa and chia seed) and legumes (like peas, lentils and chickpeas) — are also used for their protein and amino acid content. When added to a dog’s diet, these ingredients not only bring variety, they contribute phytonutrients that are considered beneficial to overall health.

Finally, amino acid fortification is commonly used to improve the protein quality and amino acid profile of dog foods. The three essential amino acids in dietary proteins that are most often in short supply are methionine, lysine and tryptophan. The other amino acid commonly fortified in pet food, especially cat foods, is taurine. Although most dogs can make sufficient amounts of taurine to meet their body’s requirements, some pet food brands, including Taste of the Wild, choose to fortify their recipes with taurine.

How Much Protein Is in Dog Food?

If your dog eats a complete and balanced diet that includes a statement from the Association of American Feed Control Officials (AAFCO) on the label, that food has been formulated to meet the nutritional needs of the pet that the food is intended for. The formula contains all the essential nutrients required (including essential amino acids), and the nutrients are present in the correct ratios for the life stage of that animal (i.e., gestation/lactation, growth, maintenance or all life stages).

How Much Protein Does a Dog Need?

AAFCO sets a minimum crude protein requirement for dog foods of 22.5% on a dry matter basis for growth and reproduction diets and 18% on a dry matter basis for adult dog maintenance diets. How much protein your dog needs depends on their age, activity level, life stage, health conditions, weight management needs and the protein quality of the diet. Excess protein in the diet is broken down and used for energy.

Keep in mind that due to health issues, some dogs may have special dietary needs that require specific protein requirements. For example, lower protein levels are recommended for dogs with chronic kidney disease. On the other hand, high-protein dog food is sometimes recommended for highly active dogs or performance dogs with high energy levels. Always consult with your veterinarian on the appropriate diet needs for your dog and exactly how much protein they should be eating.

What Is the Best Protein for Dogs?

If you have questions about your dog’s food, including the protein sources used in it, talk with your veterinarian. They can assess your dog’s nutritional needs based on age, body condition, activity level and any medical issues. Your vet can also recommend appropriate dog foods, including how much you should be feeding for proper health.
