I was wondering if some of yall could share some tuff toys besides the Kong. My 7 month old Pup doesnt show interest in it but he loves other toys. I just cant find ones that last! I went to PetSmart today and spent $15 on this 3 ring chew toy made of durable "long lasting" rubber. He has literally had it less than 20 minutes and one of the rings is chewed in half. Im half tempted to take it back, I cant beleive I spent $15 on a toy that lasted no longer than that. Any ideas?
