I have been crate training Missy, my st. bernard, for about five days now. She is about to turn 12 weeks old. She has had no accidents inside the crate during the daytime and night. I have her go straight outside when she gets out of the crate and she has no problems. I work during the daytime and play with her at night/evening. I comed home and let her out to go to potty when I get the chance. When she is free of her crate she has had a few accidents. How long does it usually take a st. bernard to potty train? IS there anything different I need to do to make this a successful expereince for her to learn w/o setbacks? Also, the other night, she started to nip. What's your opinion on stopping this behavior? Can playing w/her cause her to get rough or learn to be aggressive? How can I play w/her and not cause the behavior to happen?
