Get Your Dog Care Questions Answered by Experts
I am sorry to hear you are worried about Tina. My name is Rebecca. I am a veterinarian and will do my best to help.
What is her problem? Why do you want to give her penicillin? We do not use penicillin very often in dogs.
Penicillin is not likely to help with an eye or skin infection.
I see she is taking Bactrim, which is also an antibiotic, but can have side effects in dogs.
I am not sure what you mean by "pull her heard".
Layers of dry skin can be a skin infection, skin parasites, allergy, or autoimmune disease. Is her skin itchy? Is she scratching at all?
How is Tina doing? Can I help with or answer anything else?
