How to prevent itching in dogs caused by food

Adverse reactions to food or sensitivities in the diet include a physiological reaction (which may or may not be seen externally) or clinical signs in response to an organism’s response to the substance introduced.

How to prevent itching in dogs caused by food?

The answer may be an immune (real allergy) or a chemical or toxicological reaction which is food intolerance.

The problem is that from the outside, the reaction of the organism cannot give us an answer to the question of what it is about.

We need to follow the dog’s behavior and literally follow the clues that her behavior gives us.

It is interesting to note that no parallels can be drawn with food allergy in humans, where mainly large, complex proteins are responsible for such a reaction.

Likewise, there is no research to suggest either a genetic predisposition or a predisposition related to age.

Determining the cause

An adverse reaction to food is something that is often not recognized.

What Weimaraners should never eat

It is mostly the owners who associate the condition of their pet with the effect of a particular type of food.

They respond immediately by throwing those foods out of use. This goes no further to the vet, especially if the condition stabilizes.

Regarding the incidence of dermatological conditions, most authors consider this reaction to be somewhere between atopy and ectoparasitic hypersensitivity on the one hand, and drug allergies and contact dermatitis on the other.

Even though some breeds were seen as particularly sensitive to this reaction to food (Labrador Retriever, Char Pei, Boxer, German Shepherd), there is no research to substantiate such assumptions.

Food allergies can occur even before the first year of the dog’s life.

In this case, some foods do not have to be on the menu for long to trigger a reaction, while in some cases it may take up to two years to develop an allergic reaction.

Visible signs – itching

The most common visible sign is pruritus (itching). In some cases, it is of less intensity and localized character. Such as under the wrist on the front legs or around and under the tail.

However, in some cases, smaller fluid-filled nodules may also occur, irritating the animal and causing scratching that further leads to self-harm.

This makes it difficult to read the clinical picture by creating a secondary bacterial infection.

Pruritus can occur only on one side of the body or on both sides, and it has been observed that inflammation of the external ear canal has anything to do with food allergy and may even appear as the only sign of food sensitivity.

Likewise, pyoderma (purulent inflammation of the skin) that occasionally occurs can be a reaction, although it is not common.

Gastrointestinal tract response

There is no breed, age, or gender predisposition to manifest symptoms on the digestive tract. Likewise, clinical signs can occur on any part of the small or large intestine.

Symptoms that may (but may not) be an allergic reaction are bowel movements, stools of variable consistency, recurrent enteritis, or inflammation of the colon.

Even so, the assumption is that inflammatory processes in the gut may more often than not have been thought to be basically due to an allergic reaction to food.

How to get a diagnosis

The most practical way is to feed the dog food that he has not used before.

In this way, it found that after it, the onset of symptoms that led us to a food allergy ceases.

The further procedure is to return briefly to foods that we suspected and if symptoms return, we are diagnosed.

Weimaraner ear problems

Although it doesn’t seem very scientific, the facts show that determining an allergic reaction is neither easy nor cheap, and when it comes to intolerance, it’s even harder.

Thus, if a certain level of sensitivity is determined through tests, it is necessary to confirm it with a food test.

So, if we suspect an allergic reaction to a food, we should immediately start eliminating the components that are regularly introduced into the meal.

To make the diet more successful for the owners, a safer alternative is the use of factory-made food, which in certain components has to meet the needs of dogs, which is a basic problem of home-made food.

When it comes to a healthy dog that feeds on homemade food, with different composition, it is possible that it does not receive the required amounts of certain nutrients daily, but covers their variability on the days it receives them to a greater extent.

It is, in fact, the advantage of a healthy organism that can calculate what it has and save what is not getting enough of it.

However, when it comes to a sensitive organism while avoiding certain nutrients, the tolerance of the organism cannot be maintained for a long period of time.

The loss of certain elements in the diet that are not compensated for days and weeks may not have a good effect on the body.

That is why it is much better to use safe industrial foods that have constant amounts of certain ingredients.

However, to keep things simple, the fact is that the majority of dogs with an allergic reaction to males receive artificially produced food.

In this case, the sensitivity is caused by glycoproteins, which are resistant to heat, acid, and enzymes created by the body.

A possible variant is that due to the large number of ingredients in the food that are responsible for the maintenance of artificially produced food, the organism is in a position to be unable to recognize the glycoproteins offered to it and react to them as foreign bodies.

Why my dog is not eating

This is reinforced by the fact that, due to the increasing price of normally produced foods (without too much chemistry, GMOs or antibiotics), all kinds of ingredients are put into conventional dog food, which is treated with various means to increase digestibility, taste, smell, susceptibility to spoilage, etc. and this then leads to intolerance.


It all comes down to testing the dog for the food he eats.

Take care when giving certain foods to your dog. Watch his reactions and how he reacts to those foods. If you find that the dog has a severe allergic reaction, stop using it, and consult a veterinarian.

Do not take things lightly and leave nothing to chance, but it is about your dog’s health and life.
