We haven’t tried that yet, but I guess we could. We have done everything that we could to make his crate a “happy place”. We keep his toys in it, we feed him in it, and we give him a treat everytime we put him in so that he assoicates the crate with a good place, not a punishment or a place to go when we are not home.
The thing is, his separation anxiety is so bad that he is barking because he knows that we are home but not with him, so he barks for attention. I keep hoping that he will just adjust and grow out of it, but it has been a week since we got back from vacation and I have been awake every night.
