My 9 month old chihuahua-yorkie mix refuses to wear a collar with her identification on it. She is a very small dog, weighing 4.6 pounds, and the vet says she is full-grown.
We have tried extra-small dog collars with the collar as tight as possible, but loose enough so we can still fit two fingers beneath it. Somehow, she consistently is consistently able to get the collar wedged into her mouth and she either chews through the collar or it will get stuck in her mouth, keeping it open.
Example of her latest collar chewed through-through collar:
As you can guess, this is very concerning, we. We are worried that she will choke when it gets stuck, but we don't like leaving her without any type of identification.
How can I train my dog to be comfortable with the collar on so she doesn't try to chew it off?
