Amazing
Flavor Name: Peanut Butter, Size: 6.9 Ounce (Pack of 1)
My dogs love these so much, seems to keep my girl meatballs teeth clean. Both of them go craft for these, they chew on them almost all day, it keeps them busy. I bought other brands of these but they had this jelly filling that wasn’t safe for them, so I switched to this peanut butter one that seems a lot healthier and is a lot safer for my dogs (in a sense they won’t choke on it from basically inhaling it again 😭) and they are still interested in the bone once it’s empty, so it’s a toy that lasts forever. Overall an amazing cheap dog find on here

Great!
Flavor Name: Peanut Butter, Size: 6.9 Ounce (Pack of 1)
This is such a perfect treat for dogs! They can chew and play with it for hours. No mess or stinky smell. Bang for your buck! It lasts long but as soon as you can see any sharp edges, simply throw it away just to be on the safe side.
