I got Bella when she was 8 weeks old, and now she is 8 months. I haven't been able to get her potty trained. I feel like I've tried everything. I take her outside all the time, I give her praise and treats when she goes. However, half the time she won't go on the grass, I'll put her there and she'll walk onto the concrete and pee or poo. Do I praise her for not going on the grass since she went outside? I'm running out of ideas because she still goes in the house, and doesn't really let me know when she has to go. She also goes in her crate sometimes, so I don't think she is really crate trained. I need help!
