I have a pitbull that's 11 years old and he is starting to bark and snarl at my kids.do you put them down?

Dont be hasty. There could be a medical reason. Behavioral modification is an option. Lastly, a rescue. Never put down until you have exhausted resources.

Just turn dog in to the pitbull rescue. Nearly every breed has a rescue organization now.

I'm sure about the Oglethorpe St location. They may be able to give you some advice since there's also a medical clinic there. But the New York have location will put your dog down.
