She loves them, therefore I love them too
Size: 5.5 Inch, Color: Ring Toy
My furbaby LOVES these, especially the peanut butter flavored ones. I still regularly brush her teefers, but these do help with dental care.

Made mostly of POLYPROPYLENE PLASTIC and should not be injested.
Size: 8 Inch - 2 Pack, Color: Tree Branch
BAD PRODUCT. DO NOT BUY THESE FOR YOUR DOG. They are made mostly of POLYPROPYLENE PLASTIC. It even says on the package - "CAUTION: Product is not intended to be eaten or ingested. If you believe your pet has swallowed a piece, please take away and contact veterinarian if needed. Our dachshund went to town on one of these and had diarrhea for two days and cost us several hundred dollars in vet bills to do x-rays and medicine for the poor dog. What do you think a dog is going to do with a dog chew? Just find another product. This one isn't worth it.

It'll only last a week
Size: 5 Inch, Color: Classic Bone, Size: 5 Inch, Color: Classic Bone
We've only had it a few days and she's already half way through it. It won't last the week. She doesn't eat it, she spits out the pieces. If you buy it was a consumable, totally worth the money. I'll probably buy my power chewer a couple a month

Dog loves these over any competition.
Size: 8 Inch, Color: Tree Branch
Minnie Aussie can chew these down to a stub but takes lots of work and totally takes her stress away. Only kind I'm buying in different varieties. Yes I've tried them all for my aggressive chewer and these have been the best. I've gone through a lot of these but are lasting about week with supervision. Make sure your buddy has plenty of water and give them in 1/2 hr increments.
