Perry grieved so much when Kona passed on last November, he would go in his crate and no amount of coaxing would bring him out. Kona was quite sick and pretty old and he would lick her eyes and face during the day., he was very close to her. We just let him have his time to grieve and in a few days he came back and joined the family. Just give it a little time and maybe offer some food in your hand for a while.
