Hair loss itching
Same as always.
American Pit Bull Terriers
Hello. Thank you for contacting our service.
I saw the picture you attached.
I suspect that the cause of his hair loss and itching is most likely a parasitic infection. Has he recently applied an ectoparasite repellent? If not, it is recommended that you give him an ectoparasite repellent (Frontline, Capstar, etc.). because his skin disease looks like a parasite problem.
Benadryl is an antihistamine. Antihistamines relieve skin itching caused by allergies, but at the same time have the potential to suppress the normal immune response. Therefore, it is better to give the medicine after confirming that it is not a parasitic infection. I recommend that you make an appointment with your veterinarian. You can give your dog about 1 mg of Benadryl per pound of weight.
