Anyone know of any good dog trainers who specialize in aggression and do not cost a fortune? My dog Tank has recently started to become more aggressive and I have no idea what to do. This isn't like him, he is normally so loving and caring, I am hoping getting him neutered today will help balance things. Any helpful information or things I can do to possibly help dissipate his aggression is greatly appreciated. I love my fur baby and I do not want this to get to a point where I have no other choice than to put him down.... I don't have a lot of money so stuff I can do at home to help would be amazing. Thank you in advance for anyone willing to help me.
