I rescued my doggy, Perlita, about 7 months ago. The refugio told us that she was 1-2 years old. But I think she's probably about 1.5 years NOW. We think she's a pointer/terrier mix, but who knows. Anyways, she is really poorly behaved. The biggest problem is she doesn't come when she's called. She knows her name, knows I want her to come, but won't because she doesn't want to. I take her to a fenced park to run around and I always bring treats with me. When I call her I give her a treat. If she can tell I'm not going to give her a treat, or if she knows I don't have treats, she'll come and stop 5 feet away, look for a treat, then run away! Even if I'm pretending to hold a treat, she can tell I don't have one. I've even tried picking up a tiny rock to offer her, and she can tell from 5 feet away it's not food. I call her multiple times while at the park so she doesn't think we leave every time I call her. But she still won't come. I don't dare let her off her leash unless she's enclosed in a fence. I don't know what to do! She walks great on a leash, always sits for me when I put on the leash and take it off. So she knows how to behave, but she refuses to come when I call her! My "backyard" is only about the size of a small bedroom, so there's not a whole lot of stuff I can do back there with her. Any ideas? I'm trying to avoid paying for expensive doggy lessons.
