About two months ago, my grandparents got a fine purebred Golden Retriever, and we started training it about a month and a half probably. We decided that we did not want to spend mony on our own treats, so I got the bright idea to give him an ice cube when he sat or lied down, etc. We do use treats with our other two dogs, wich are shi-zhu hounds, although they do not do as many tricks as Oso (the golden retriever), it is alot cheaper.
