Honey Girl, a terrier/dachshund* mix, is a chewer. She always has rawhide to chew on and play with. Otherwise my shoes are not safe, in fact, nothing in the condo would be safe. I check her poop and it doesn't appear to upset her digestive system. She doesn't foam at the mouth or vomit, either. If it ain't broke, don't fix it.
*Hubby thinks the terrier part is probably Fox Terrier, so he calls her our "Foxy Dachsie."
