ok i have another question. my brother  has a red mini pin. we have gone through 2 harness's already cause she has chewed them off of her. he puts her outside on a tie down in the back yard cause she can squeeze through places in the fence and get out and she did that one time and got lost when it was raining and storming one night. anyway does anybody have any suggestions bout what he can use for her so she does not chew it up and get out?

I bought Tinkerbelle a thicker leather collar.  She was scratching and chewing at the others until they just fell apart.  She still can chew the very end of her collar, but it has lasted the longest.
