i recommene the 12" ones, they last longer.. dont forget , when they get
really small, you have to throw them out.. we want them to choke on it ok.
go on line for cow hooves also, they love them too.. it might be cheaper to go to your local pet store.. try this websit,,
petsboutique@aol.com.
also they love the bully burgers..and they love love love the chicken health wrap. 8", dont know if they still have them
