Dogs Love!
Color: Real Bacon&Beef
My dogs love these. I originally had ordered one but the 3 dogs kept stealing it from each other so I had to buy more. I purchased 2, 2 packs. Highly recommend if you have some chewers. Great quality for the price. They do seem to last a while as well. Highly recommend.

they are indestructible
Color: Real Bacon&Beef
these chews can definitely stand up to an aggressive chewer. they are extremely hard and will probably last for months, maybe a year or more. but because they are so indestructible, they are the last of the chew toys that my pitbull will go for. i appreciate that he will sometimes tackle one for a while. he prefers the hardest rubber kong-type chew toys. they are not indestructible, but it takes a while for him to wear them down and destroy them. i will probably not buy these indestructible chews again (bought 2-3 packages already), but if you have a big headed dog with lots of really strong teeth and jaws like a vice, they might be right for your pet.
