Scratching in any area of the body is usually the first sign of an allergy in dogs. Sometimes mistaken by pet owners as a simple skin condition due to the use of a new shampoo, or an encounter with an irritating plant while out on a run in the field, milk allergies in dogs can be overlooked. Milk and other dairy products are known to be one of the top allergens found in dog foods. Pet owners may also have the habit of allowing their pet a sample of cheese, ice cream, or milk on a regular basis. Many pets tolerate, and in fact enjoy, the taste of a milk based product on occasion. 

Documentation shows that dogs of any age can develop allergies. Typically an airborne allergy such as pollen will develop at an early age but allergies to food can develop at any time in a dog’s life, with senior dogs being more prone to food allergies. Any time an older dog is experiencing skin issues, food allergies should be considered. In addition, with younger pets, the presence of an allergen should not be overlooked when evaluating itchy, red skin. Diagnosing and treating an allergy to milk can be a timely exercise; patience and perseverance will be required.

Allergens are substances that can cause an inflammation that results in effects such as itching, hair loss, and dermatitis. Canines of all breeds can have allergies to milk that will lead to secondary complications, occurring because of the allergy symptoms.

Symptoms of milk allergies in dogs will differ between canines. Many of the signs of allergies that will be seen in dogs can mimic other illnesses. Be certain to have any display of discomfort or unusual behavior checked by your veterinarian without delay in case there is an underlying disease course in progress, and to limit your pet’s agony and distress.

It should also be noted that dogs can be fed a food for weeks to months (even two years in some cases) before symptoms of allergy appear.

Milk allergies are one of the most common types seen in dogs, the others being beef and wheat. Breeds that are thought to have a predisposition to allergies are:

The diagnostic process for determining a food allergy is not a simple one. The first step may be to do a full health evaluation, starting with a history of your pet’s recent illnesses, travel history, activity level, typical diet, and bowel and urinary habits. It will be helpful to the veterinary team if you are able to provide detail as to when the symptoms started and exactly what signs of illness or discomfort prompted you to make the veterinary appointment.

Tests that may be run initially are a complete blood count, serum chemistry analysis, electrolyte panel, fecal analysis, and urinalysis in order to verify if there is an underlying illness that could be causing symptoms similar to allergies. If your pet has dry skin patches, the veterinarian may do a skin scraping to be checked under the microscope for abnormalities or the presence of mites or bacteria.

Some pets may have ear infections and skin infections that run concurrently with an allergy; the veterinarian will check your pet’s ears, eyes, nose, mouth, and skin to evaluate the extent of these conditions. If your pet is suffering from severe gastrointestinal symptoms, the veterinarian may recommend additional testing in case inflammation needs to be addressed.

Finding out if your pet has an allergy to milk can be a lengthy process. Your veterinarian can guide you through the steps. Elimination diets involve removing the suspected allergen from the diet for a period of up to three months. This may seem like a daunting task but fortunately, many dog food producers now offer several food options for pets who have sensitivities.

You will need to avoid feeding your dog anything containing dairy products during the trial. Studies show that the case with most dogs is that improvement in their condition will be evident after four to six weeks. However, elimination trials may be continued, at the discretion of the professionals at the clinic, for a period of at least eight to twelve weeks. An elimination trial means all sources of food must be monitored, including snack items such as dog biscuits and treats. All members of the family must be aware of the importance of adhering to the rules, or the elimination diet will not be successful. Once your pet seems to be on the mend, suspected ingredients will be slowly added back into the diet in the attempt to determine the culprit.

If your dog has concurrent issues like pruritus or other secondary skin irritation, or a condition such as ear infection, medications will be prescribed to begin the process of providing relief for your canine companion.

Once the allergen is eliminated from your dog’s diet, the recovery should be straightforward. Care on your part to read all ingredients and avoid milk products when purchasing food items for your pet will be essential. Soon this will be second nature. If you have a doubt as to whether a food item is suitable for your dog, do not make the purchase. If you see any concerning changes in your pet’s demeanor, be certain to contact your veterinarian for a follow-up appointment.
