Updated On September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Female | unspayed | 2 months and 29 days old | 5 lbs

What allergies could my dog have? I would like just a brief description of the possibilities. She is 3 months, 5lbs, a yorkie. Only goes outside to go to the bathroom. She scratches a lot, I've noticed. Even after being put on Trifexis.

Allergies can occur due to various factors, it could be something in the food, something outside in the environment or something that comes from inside the house (storage mites for example). it is usually very difficult, sometimes impossible to find the cause of the allergies.
