Jenna rescued us when she was 3...she is now 5 1/2 she knows, sit, down & stay, walks on a leash well(that's all i bothered to teach her) and is very well behaved when we take her out to parks, etc. she was a puppy mill breeder...it took a few weeks to house train her but it didn't take her long to settle in and take over the house....seems like i've had her forever...best dog i've ever had...I know I was lucky to get such a good rescue (without issues)...I think from now on i'll always adopt a rescue
