Hi, I had posted previously about a stray that I have taken in & need help in understanding why he growls at strangers who try to approach him, and how to correct this, making him adoptable to a good home. He knows and obeys commands, I work with him several times a day, reinforcing sit, stay, come, down. Since he seems to be untrusting, when I walk him with my 4 dogs, I had been walking him on a short leash, which he did pretty well with. To try and socialize him more with my dogs, I have started walking him on a 25' rope, so he could run with the others, plus get an idea if he would still come when called, etc. He has done really well with that, except that when my dogs romp and play, he gets agitated & I think this is because he never "played" with other dogs before & thinks they are fighting. Right after I brought him home he and my male alpha dog fought, so I have been trying to socialize him with mine, more slowly. He seems to do okay (still apprehensive) when I try to socialize him by taking him to local pet store, car rides, etc. I can't really say for sure what he would do if someone tried to pet him because I have not allowed that to this point. I have been trying to follow the Alpha rules per Sit/Stay/Fetch, but it's hard, since he is pretty good in all those areas. He is actually almost perfect except for his extreme aggression with strangers. I am sure that he was an only dog that wasn't socialized.
I have put alot of money into Buddy, neutering, shots, etc. I can't afford to have to pay for a behaviourist, but I really feel that he would make someone a wonderful, loving pet - if I can just rid him of the aggression. My problem is that I can't figure out if it is dominance, fear, or what - but, it is truly vicious behaviour and I am convinced that he would attack any stranger that set foot on our property or tried to approach him. Like I said, out & about, he is fine.
I would appreciate any tips or suggestions as I am so frustrated! I want to help him, but don't know what to do! Thanks!
