It doesn't necessarily have to be a food allergy. 2 of my dogs have seasonal allergies. They are allergic to pollens in the air at certain times of the year. My Jack Russel is really seasonal specific, she only itches in the late summer, early fall. She is itchy for about 2 months and when it gets colder she just stops. My golden on the other hand began with seasons, spring and fall, and the older she got the worse it got until she itched all the time. I had her skin tested by a dog dermatologist and she was allergic to just about everything and I had to give her serum injections for about 2 years. She doesn't get the shots any more and doesn't itch nearly as much as she used to. |
