Only Eating In Private
A dog refusing to eat when there is another human or dog in the room is a doggo that is unwilling to share their food. We humans do not think about this as dog food is not something we eat, but dogs do not know that!
Voluntarily Sleeping In His Crate
If your dog likes taking naps in his crate, that is probably because they feel like it is their bedroom. Do not take it personally if they choose the crate over your own bed or the couch. Your pooch feels more comfortable and at ease in the crate, since they stay there if you are not home. For them, it is their own space.
