My oldest APBT had horrible seperation anxiety. he would chew anything that belonged to my husband and I. Shoes, coats, hats, you name it he would tear it up. So we thought maybe he needed more exercise nope that didnt work, so we got him a friend. Since we got Lollie he has only tore up one thing and well it was totally my fault. I left it out and should of known better. Needless to say my feather pillow is no more. =) As far as Kong’s go my puppies have 4 of them and love them. You can even freeze them and make popsicles for your puppies!
