Playful loving guard dog (Okmulgee)

I am looking to re-home our pit mix. He is to much for me to handle and care for. He is playful and loving and good around my two Chihuahuas. He would make someone a really good guard dog. He has some raw places on his ears from flys landing on them and I have been trying to put an antiseptic on his ears but he does not like it.. When I found him he had been dumped at my mom's and was skin and bones. I couldn't leave him in that condition.
