Itchy Skin
This is a common symptom where dogs frequently scratch, bite, or lick their skin to relieve itchiness.
Inflamed Skin
Inflammation can lead to red, irritated, and sometimes swollen patches on the dog's skin.
Ear Infections
Dogs with allergies often experience recurrent ear infections, which can lead to scratching at the ears, discharge, or odor.
Runny Eyes
Allergic reactions can cause watery or runny eyes in dogs, often accompanied by redness or irritation.
Sneezing
Frequent sneezing is another indication of allergies in dogs, similar to how humans react to allergens in the air.
Gastrointestinal Issues
Some dogs may experience diarrhea or vomiting as a symptom of allergies.
