Pet Sitter Job in San Antonio, Texas

Fionn is 3 years old and for the first 2 years of his life he loved everyone and everything. Around a year ago he had a bunch of big life changes (including losing his packmate and a move to a big apartment complex) and started having fear aggression issues. He barks and growls at strange people and dogs while on walks, in the car and even when he hears them outside the apartment. He even occasionally lunges at dogs. He is always "on watch" and anxious when outside our home and even has anxious moments inside if he hears people outside. He has not bitten anyone, but I really want his quality of life to be better than it is now, for him to be able to go out with us again.
