to the site. Bullies tend to be OCD and many don't like change so you will have to give him time and space to settle in. Hopefully one of the first things you will do is take that choke chain collar off of him and throw it in the trash as these guys have a hard enough time breathing on their own to begin with and don't need any more help restricting their airways. Other than that give him plenty of love and attention and he will eventually settle in. Several members here have rescued and adopted older bullies without issues and they have settled in quite nicely. How long that will take though depends on each dog. Could be a few days, week, or a month or longer.
