Can Dog Treats Cause Diarrhea? What Every Pet Parent Should Know

Dog treats are meant to be a fun reward, a little moment of joy in your dog’s day. But sometimes, that “happy snack” can lead to something not-so-happy—diarrhea. So the question is real: can dog treats cause diarrhea?

Short answer: yes, they can—but it usually comes down to what’s inside the treat, how much is given, and your dog’s individual sensitivity.

Let’s take a closer look.

Why Dog Treats Can Upset Your Dog’s Stomach

Dogs have sensitive digestive systems, and even small changes can throw things off. According to the American Kennel Club (AKC), sudden dietary changes are one of the most common causes of digestive upset in dogs (https://www.akc.org/expert-advice/health/dog-diarrhea/).

Dog treats can cause diarrhea for a few main reasons:

1. Too Much of a Good Thing

Treats are not meant to replace meals. If a dog eats too many treats—especially in a short time—their digestive system can get overloaded.

Think of it like this: if a dog’s diet suddenly becomes rich in snacks, their gut bacteria may not keep up, which can lead to loose stools.

2. Rich or High-Fat Ingredients

Some treats—especially those made with liver, egg yolk, or fatty meats—are very nutrient-dense.

While these ingredients can be beneficial in small amounts, too much fat can trigger digestive upset. The VCA Animal Hospitals note that high-fat diets can contribute to gastrointestinal issues, including diarrhea and even pancreatitis (https://vcahospitals.com/know-your-pet/pancreatitis-in-dogs).

For example, treats made with beef liver or egg yolk are packed with protein and fat. That’s great nutritionally—but portion control matters a lot.

3. Sudden Diet Changes

Switching from one type of treat to another—especially if the new one has different ingredients—can confuse your dog’s gut.

The Cornell University College of Veterinary Medicine explains that abrupt dietary changes can disrupt gut flora, leading to digestive problems (https://www.vet.cornell.edu).

4. Food Sensitivities or Allergies

Some dogs are sensitive to ingredients like:

• Chicken
• Beef
• Eggs
• Grains

If a treat contains something your dog can’t tolerate, diarrhea may show up as one of the first signs.

That’s why brands like Kaiivo focus on single-ingredient treats—like freeze-dried chicken or quail egg yolk—so pet parents can better identify what’s in the bowl and reduce unnecessary additives.

Do not use Kaiivo freeze-dried pure quail egg yolk treat in dogs allergic to egg. Consult your veterinarian before use in dogs with chronic kidney disease.

5. Artificial Additives or Fillers

Lower-quality treats may include artificial colors, flavors, or fillers that are harder for dogs to digest.

Clean-label treats—like those from Kaiivo, which emphasize “no fillers, no artificial additives”—are generally gentler on digestion because they stick to simple, recognizable ingredients.

What About Freeze-Dried Treats?

Freeze-dried treats are becoming super popular—and for good reason.

They’re made by removing moisture while keeping nutrients intact. This helps preserve the natural flavor without needing preservatives.

Brands like Kaiivo use freeze-dried formats for ingredients like:

• Chicken
• Beef liver
• Quail egg yolk

These are nutrient-rich and highly palatable, but because they are concentrated, they should always be fed in moderation.

Ingredient Spotlight: When Good Nutrition Needs Balance

Some ingredients commonly found in dog treats offer great benefits—but they can also contribute to digestive issues if overfed:

Egg Yolk

Egg yolk is rich in protein and fat, including lecithin, which supports skin and coat health. However, its high fat content can be too much for sensitive stomachs if given in excess.

Beef Liver

Liver is packed with iron and vitamin A, supporting energy and immunity. But it’s also very nutrient-dense—too much can overwhelm a dog’s system.

Chicken

Chicken is generally easy to digest and commonly used in treats like those from Kaiivo. But dogs with chicken allergies or sensitivities may still react with digestive upset.

How Much Is Too Much?

Even the healthiest treat can cause problems if given in large quantities.

A good rule is:
Treats should make up no more than 10% of your dog’s daily calories.

If your dog is getting too many treats—especially alongside a full meal—their digestion may struggle to keep up.

Kaiivo’s feeding guidelines, for example, recommend specific daily amounts based on your dog’s size. This kind of guidance helps prevent overfeeding and keeps digestion stable.

Signs Your Dog’s Treats Might Be the Problem

If you notice any of these after giving a treat, it could be related:

• Loose stools or diarrhea
• Increased gas
• Vomiting
• Loss of appetite
• Lethargy

If symptoms are mild, it might just be a temporary reaction. But if it continues, it’s worth reassessing the treat or consulting a veterinarian.

How to Avoid Treat-Related Diarrhea

You don’t have to give up treats—just use them wisely.

Here’s what helps:

Keep It Simple

Single-ingredient treats (like those from Kaiivo) are easier to digest because there’s less for the body to process.

Introduce Slowly

When trying a new treat, start with a small amount and watch how your dog reacts over 1–2 days.

Watch Portion Sizes

Even high-quality treats can cause issues if overfed. Stick to recommended serving sizes.

Make Sure There’s Fresh Water

Freeze-dried treats absorb moisture. Dogs should always have access to water to help digestion.

So dog treats can cause diarrhea, but usually only when something is off. When you choose carefully and feed in moderation, treats can be a safe and enjoyable part of your dog’s routine.

Brands like Kaiivo focus on clean, simple, and plant- and protein-based recipes to help support everyday pet wellness without unnecessary fillers. And that’s exactly the kind of approach that can make treat time both fun and gentle on your dog’s stomach.
