Peanut butter can get everywhere. If your pup has ever had a peanut butter treat inside of the crate, some of it may have gotten on it. Of course, this explanation of why do dogs lick their cage would only be as long as the peanut butter remains.

Risks of Dogs Licking Their Cage

Licking a crate isn’t free from risks. When licking any material for a prolonged amount of time, it can cause small pieces of it to come off into your dog’s mouth. Whether its metal or wood, it can cause injuries inside of your dog’s mouth or somewhere inside of the body, similar to a piece of string, glass, or another foreign object.

Excessively licking the grates on the kennel should not be ignored.
