My dog is almost 1 years old she is a boxer/black lab. We got her when she was 8weeks old. We already had one dog and now they are a year apart, they are best buddies. We have recently started leaving the older one out of the crate. The younger one cannot be trusted yet alone, afraid she will tear the house apart. So we only crate her when we're at work. But every time we come home there is tons of slobber inside the crate, on the carpet surrounding it and all over her, not to mention the horrible smell from it. I dont know why she does this or how to make it stop. We put treats and bones in with her to try to keep her occupied but it doesnt seem to be working. I have no idea what to do. Can anyone help me?
