The Indications of a Sensitive Stomach

Generally, dogs with sensitive stomachs present a similar set of symptoms. However, while each dog is unique, some dogs experience some symptoms more often than others. Nevertheless, if your dog exhibits any of the following signs, she may have a sensitive stomach:

  • Vomiting – While the occasional episode of vomiting is typical (dogs have a "eat first, barf later" philosophy). Frequent bouts of vomiting generally signal that your dog has a sensitive stomach or a significant health condition.
  • Diarrhea – Loose or watery feces are another symptom that occasionally affects all dogs. Still, their recurrence suggests a sensitive stomach or a more severe condition.
  • Gas – If your dog often engages in chemical warfare, she probably has a sensitive stomach (and, let's be honest, so do you). Gas-x can help alleviate symptoms, but you should ideally fix your dog's gastrointestinal difficulties at their cause.
  • Lack of appetite - Does your tiny eating machine refuse food? Stomach sensitivity is frequently indicated by a chronic lack of appetite. Your veterinarian may recommend modifying your dog's food to ensure they receive the necessary nutrients and energy.
  • Weight Loss - If your dog is allergic to particular foods, he may not enjoy eating them. It is typical for pets with digestive difficulties and stomach allergies to lose weight.

Ingredients to Avoid

Knowing the signs makes it simpler to determine if your dog has a sensitive stomach. When picking the proper nourishment for your pet, you should be cautious and pay close attention to the contents.

Here is a list of things that can disturb the sensitive stomach of your dog:


Milk and other dairy products are commonly enjoyed by dogs, but not all can digest them. Some individuals may develop acute intestinal distress with vomiting, diarrhea, and gas.

It doesn't matter how much your dog like dairy products if he has lactose intolerance. Additionally, avoid items that list dairy as a primary ingredient.


Fruits are a nutritious snack for both humans and dogs. However, dogs with sensitive stomachs may struggle to digest fruits with high sugar content. The sugar might aggravate stomach irritation and create digestive issues.

The maximum fruit content for kibbles and blends should not exceed 10 percent.


Most dog foods made for dogs with sensitive stomachs do not include gluten. They do not contain grains such as wheat, spelled, rye, or barley, which could significantly contribute to your pet's digestive issues. Most dog owners prefer gluten- and grain-free dog food to avoid various inflammatory health conditions linked to the components.

Why Do Dogs Have Sensitive Stomachs?

Your dog's sensitive stomach could be caused by several factors, and you'll need to undertake some detective work to establish which ones are the most problematic. You should study the things that regularly upset dogs' stomachs as much as possible. Still, some trial and error will also be necessary.

However, it may be impossible to definitively pinpoint the source of your dog's digestive problems. In such circumstances, you will simply need to choose a dog food that your dog can readily digest.

Four of the most common causes of gastrointestinal sensitivity in dogs are:

1. Some of the Proteins and Fats in Your Dog's Food Are Indigestible to Him.

Dogs with sensitive stomachs may be unable to digest certain protein sources or excessive amounts of fat. So choose readily digestible proteins such as chicken and lamb and avoid high-fat dog meals and table scraps.

Suppose your dog's digestive difficulties result from eating something uncommon (something he isn't frequently fed). In that case, his upset stomach can be soothed with rice or other simple meals.

2. Some Proteins in Your Dog's Diet Trigger an Allergic Reaction.

Food allergies typically produce skin or ear symptoms but can also cause gastrointestinal distress.

Typically, food allergies are treated with an elimination-challenge diet. This entails removing all common allergens from your dog's diet until the problem is addressed and assessing her reaction when each allergy is reintroduced individually.

3. Your Dog Is Unable to Digest the Treats' Ingredients.

Like their diet, dog treats may contain substances that disrupt the digestive function of your pet.

Additionally, giving your dog too many treats can cause her body to get overloaded. While attempting to treat your dog's sensitive stomach, avoid giving him goodies. When you are ready to reintroduce treats, consider hypoallergenic options.

4. Your Dog Is Experiencing Emotional Turmoil.

Acute and persistent stress and worry can also cause your dog's digestive system to struggle. Keeping track of your dog's events, meals, and eliminations may help determine the cause. It may also be beneficial to offer your dog a cozy den to retreat to after meals.

Changing the Dog's Food for a Sensitive Dog

Slowly transferring your dog from one food to another is generally a good idea. Still, it is especially crucial for dogs with digestive issues. Changing this dog's diet abruptly is a recipe for extra issues, so be sure to do so gradually.

Most veterinarians advise beginning the transition by feeding your dog a bowl containing 80 to 90 percent of their old food and 10 to 20 percent of their new food. The following day, increase the percentage of new dog food to between 30 and 40 percent while decreasing the amount of old dog food to between 60 and 70 percent.

Continue this manner until your dog receives 100 percent of the new food; the entire procedure should take between 5 and 7 days.

Not all dogs with sensitive stomachs may experience gastrointestinal distress due to new dog food. And the diet may even yield favorable outcomes relatively rapidly. In such situations, it may be prudent to speed up the transition. You'll just have to use your best judgment.
