Get Your Dog Care Questions Answered by Experts
I am Dr. Snow, and I can try to assist you today with Chato! What kind of flea treatment is he on? Is the wound right at the base of the tail?
Sometimes if they are uncomfortable from a wound it can cause them not to eat and act normally. You can try cleaning the wound with a mild antibacterial soap, or a 50:50 combination of white vinegar and water, and then apply some triple antibiotic ointment.
Your local pet store should also carry a medicated shampoo that can be used.
If he is very itchy, you can give Diphenhydramine (Benadryl) orally at 1mg per pound. Just make sure the only ingredient is the Diphenhydramine.
You can try to entice him to eat by offering a bland diet, such as boiled chicken and rice, plain yogurt, and cottage cheese.
