Dog Lactose Intolerance Symptoms: What to Look Out For

Section 1: Canine Lactose Intolerance Symptoms

1. Diarrhea

Diarrhea is one of the most common signs of lactose intolerance in dogs. While a healthy dog's feces can form into clumps, lactoseintolerant dogs will have stools that resemble water. An increase in the frequency of bowel movements could indicate lactose intolerance and subsequent diarrhea.

2. Vomiting

3. Loss of Appetite

Typically, dogs have a regular eating pattern. As long as they're not overindulging in treats or being picky, they usually finish what's in their food bowl. However, if a dog is lactose intolerant, this changes. They may lose their appetite due to gastrointestinal discomfort, feeling nausea, and being unable to eat.

4. Bloating

Dogs' intestines can expand to accommodate bacteria and the fermentation of sugars, producing gas. But when there's an excess of gas, they can become uncomfortable due to bloating.

5. Flatulence

Bloating may not always be noticeable, but it often leads to increased flatulence in dogs. Lactoseintolerant dogs may experience more frequent flatulence after consuming dairy products. While it might seem amusing, it's important for owners to recognize this as a sign of discomfort in their pets.

Section 2: Canine Lactose Intolerance Allergic Reactions

1. Itchy and Red Skin

Just as humans can experience itchy, red skin from an allergic reaction, so can dogs. After drinking milk, a lactoseintolerant dog might suddenly start scratching or licking their paws. It's crucial to note that this could be a sign of milk allergy, which may also manifest as skin redness.

2. Erythema Multiforme

Dogs with dairy allergies may develop a rash known as erythema multiforme. This can be triggered by an immune system response to dairy, leading to skin diseases. The dog may become excessively itchy, chew at their skin, and experience hair loss. In severe cases, there may be skin desquamation and ulcers.

3. Swelling of the Face

A small number of dogs may experience facial swelling after consuming milk. If this occurs, dog owners should discontinue feeding dairy products.

4. Difficulty Breathing

In severe cases of dairy allergy, dogs may exhibit difficulty breathing and could even go into shock. In such instances, pet owners must seek immediate veterinary care.
