Immediate Doggy Happiness!
Flavor Name: Bacon, Size: Medium
Great dog bones! These are a nice size for my 55-pound Aussie, as well as our 96-pound Alaskan Shepherd. They are big enough to last for a while, and big enough to see so that I don't step on them with my bare feet; part of this is that they stick up off the floor a bit, instead of being a flat bone, all in one plane.

Nice size, the quality is changing. It is softer I believe than it used to be.
Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large
Not sure if something has changed in the way this product "Barkbone" is made. I bought this many times before and it lasted. Today, on my dogs first day of use, he had chipped through the material, and already destroying it. he has had it for less than 3 hours.

Perfect for small senior dogs!
Size: Extra Small (Pack of 1), Color: Pink
So I actually bought this for my senior Bolonka. She has a neurological disorder that does not allow her to have hard bones or treats, plus I am trying to protect her teeth for as long as I can. This is a GREAT toy. I like to fill up the middle with yogurt or peanut butter and things she can lick instead of bite into. This is the PERFECT size for her. She likes to play with it even without a treat on the inside. She just carries it around the house , as its not heavy at all, and throws it around, it is too cute! It is not loud at all, the only noise that comes out is if shes got a ton of saliva and her teeth rub against it. I just pulled it off the packaging, washed it, and it was ready to go. It will last forever with my baby because she doesn't chew hard so I am unsure about the durability for bigger pups or dogs who are heavy chewers. I am so glad I got this for her and I would HIGHLY recommend it!
