We have 2 Bull Terriers. They have ruined EVERY single toy we've purchased, to a total of well over $250! We purchased the Hurley because of the guarantee. They got the toys for Christmas (we also purchased the Huck) and they are still perfect. Tinkerbell and Boo love to play tug with the Hurley and can chase the Huck for hours. THANK YOU for a truly tough toy our bullies can enjoy! I have told many friends about these products, as well!
