When I was home two weeks ago I got a gift card to petco for $40 and I bought Tucker a bunch of stuff (though not as much as I thought I'd be able to get for $40). I got him a hoof, pig ear, tire biter, one of the toys you put water bottles in, and maybe something else, can't remember. Anyways I was talking to my mom today and, among several other Tucker related complaints, she said his chewing has become ridiculous (she used the word obsessive), he can now easily eat an entire bully stick in one day which is of course a problem. So I asked if he was using the tire biter I got him. She said he had destroyed it already So yeah, I need some ideas. They need to be enjoyable to chew (he LIKED the tire biter) but durable and the rights size for a 15 pound dog.
