My pitbull has an itchy mouth and red eye. Is it allergies or fleas?

Updated on September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Male | neutered | 45 lbs

Adopted a pitbull, 2 years old from shelter last week. He has been itchy at his mouth nonstop. When we came home today his eye was red with a little bump. Not sure if it was from excessive scratching but I'm worried there are no clear signs of irritation other then red eye on one side and red skin near his mouth

Scratching and itchiness can be caused by various reasons such as fleas, mites ,fungal infection, bacterial infection and allergies. the first 4 needs to be ruled out before we start treating for allergies. in order to do that first de-flea Panther with a high quality flea treatment such as advantage spot on, if it doesn't help - take him to the vet in order to check for/treat the other possibilities.

If everything is ruled out, then an allergy treatment can be started. Usually an hypoallergenic food is a good way to start together with anti histamines. if it doesn't help - the best solution is a medication called Apoquel which treats allergies with great success and without side effects.
