How Do I Stop or Prevent My Dog from Chewing on the Crate?
Give them an appropriate toy to chew or occupy them while they are in the crate. A treat stuffed kong is durable, safe and fun for puppies to chew on ultimately deferring their attention from the crate bars.
If you have adopted a dog that is afraid of the crate, it is possible that he had a negative experience in the past that he is associating with the crate. Thankfully there is a chance this can be changed with teaching a new, positive association.
If you think your dog is suffering from separation anxiety, a crate may not be the best place for containment. Many dogs will hurt themselves just to get out of the crate. You should seek help from a professional like an animal behaviorist or trainer.
Crate Time Length
Most pet professionals will recommend that you not leave your dog in the crate for longer than 8 hours. If you work and 8 hour day this seems almost impossible to manage. Hire a dog walker to come in the middle of the day to give your dog a break from the crate. Another solution is to take your dog to daycare while you are at work.
Don't ignore your dog when he bites on the crate bars. He is trying to tell you something.
How Does It Affect My Dog's Teeth?
Crate bar chewing for puppies and adult dogs over long periods of time will cause their teeth to become worn down. This damages the tooth, which may cause it to die and eventually need to be removed.
We were getting Cairo's heartworm test and the veterinarian noticed his tooth. She asked if he used to bite on crate bars. She said she could tell and the tooth may eventually need to be removed. She mentioned that if the tooth turned white in color, it is no longer alive.
The American Veterinary Dental Society mentions:
"If the wear occurs slowly, the tooth will respond by laying down extra tooth structure (dentin) in response to the tooth loss to protect the pulp. This is similar to the way that our teeth respond to deep cavities."
It is important for pet parents to check your pet's mouth monthly for oral abnormalities.
