Please help with my 1yr old Jindo, he has been biting his buttocks at the base of the tail lately. He actually bit and pulled a big chunk of hair out, literally bald. I was wondering if anyone else have noticed this type of behavior on their dog? if so, please help with any solution. It was a real struggle for me to clean up his wound and patch it up so it wouldnt get infected, but he continues to bite it whenever I take my eyes off him. The last time I caught him biting himself on the spot it was bleeding.
Thank you for your time and solution,
Take him to the vet asap. Allergies will cause this, as will hot spots and other issues. He may just need some allergy medication but you'll have to find out for sure.
