Agree with Maximo.
We use bully sticks and Himalayan chews here. I've never seen the Himalayan's at Petsmart, they are usually only in pet specialty stores, but they are pricey (worth it, though, because they last a while). I order from RDB911 here on YT and they are a GREAT price with free shipping! Jackson loves his bully sticks, which I buy in bulk from
Bully Sticks - All Natural Dog Treats - Best Bully Stick... I find pet stores way over charge for them and some can be really smelly!
But good luck. Jackson is 2 1/2 years old and still loves finding grass and anything else outside to eat or chew.
