This is the same medication as Benadryl. Here is info on using it in dogs: https://www.petcoach.co/canigive/dog/benadryl/ Personally, I don’t think that Benadryl is very effective for dog allergies. If you are concerned about allergies in Mylee, I would discuss other medications with your vet. According to the article, she would need 5mg, or 1/5 of one of these tablets.
