Food Intolerance in Dogs

Updated: Mar 1, 2020

Food intolerance symptoms in dogs involve unusual clinical manifestations to a certain diet. In a nutshell, a dog that experiences food intolerance is incapable to ingest, absorb, and use a certain foodstuff.

Dog food intolerance to some variety of diet is normally because of unclear reasons. However, they may be as a result of certain additive, ingredient or dietary composite. Besides, there could be a possibility of a response to the toxic influences of a particular contaminant in food or spoiled food.

When it comes to food intolerance in dogs, breed, gender or age doesn't matter. Seemingly, all dogs are not immune to food intolerance. Notwithstanding, Gluten intolerance is has been witnessed in Irish setters. On the other hand, lactose intolerance appears to be common in mature dogs.


The easiest way to note food tolerance in your dog is when you introduce a new source or foodstuff to your dog's menu. Sometimes, the condition might be a little bit tricky to notice since the clinical symptoms may disappear in the dieted state or within the first days of different dietary changes. The obvious symptoms of food tolerance involve:

  • Vomiting

  • Abdominal gas or Flatulence

  • Diarrhea

  • Lack of appetite

  • Weight loss

  • Discomfort caused by abdominal pain

  • Itching or scratching unreasonably

  • Poor weight gain

  • Poor body state

In most instances of serious dietary reactions, there is a record of unexpected diet change. Rather than foods themselves, your dog could just be reacting to the food coloring, additives, propylene glycol or spices. Should this be the case, the symptoms may not be manifested through the above-listed indicators.

Food intolerances in dogs do not have an immune element. While examining the symptoms that your dog exhibits, it is quite essential to keep in mind that poorly digested food can manifest gurgling, gas and nausea. That means one needs to be keen as determining whether the reaction is immune driven could be a challenge.

Once your dog exhibits these dog food intolerance symptoms, it can take several weeks to determine what the rejoinders are due to. More so, it can still take another week or more to find out the origin of the response. Normally, it takes a minimum of 8 weeks of feeding to establish an ideal diet should your dog develop a serious intolerance to food. In a few cases, it can even take about 36 weeks. This involves visiting your vet, specialized diets, and probably waiting for the offensive dog food intolerance to fall.
