I have a problem, and need HELP... Ever since I left my dog with my ex *he was my boyfriend at the time* for two weeks over a year (closer to two) ago he came back a different dog. Now, almost 2years later he has slowly become more and more aggressive towards people. Very few people can come into my home, or even approach him to pet him. What can I do to fix this? I have been trying to socialize him, but he lashes out when anyone but my close friends come near him. Heck, some people cant even walk by my house. I want to get him fixed, but cannot afford it I barely make enough to pay my bills and rent only work three shifts a week and those are never more than 4.5 hours a shift.
