B cells are stem cells that are found in a dog's bone marrow. Antibodies that are within the white blood cells can identify viruses, allergens, or parasites that shouldn't be in a dog's body. Immunoglobins within the body can determine when these antibodies are present. The antibodies can cause inflammation, irritation, redness, and excessive itching.
Types Of Allergies And Symptoms They Cause
A lot of pets develop allergies to certain types of food. However, a change in your dog's diet can usually alleviate the symptoms of food sensitivity. When a dog develops an environmental allergy, it often manifests at between one and three years of age. Symptoms may include:
- Licking or chewing paws
- Ear infections
- Hair loss
- Scratching or itching
