Extremely durable but too large for our Aussie
Color: Bacon -Blue
This toy is very solid and seems like it would hold up well for aggressive chewers, but it ended up being too large and heavy for our Australian Shepherd. He had trouble comfortably holding it in his mouth and wasn’t very interested in chewing on it because of the size and weight. The quality itself seems good, but I would recommend it more for larger dogs with bigger jaws that enjoy heavier chew toys.

Indestructible toy
Color: Bacon
This is a great toy. I have a husky pit bull mix puppy that can chew anything. I swear that dog can chew the varnish off a furniture. He cannot chew this up.I highly recommend

Beloved But Beware Microplastic Chip-Offs
Color: Bacon
My doodle adores this thing and gnaws on it constantly. He has not been able to harm it, which is great. That’s the best part. Things to be aware of: 1. This is mostly molded plastic; it is a bit heavy and very hard. My dog tosses it into the air and if it lands on him, it HURTS. A lot. 2. While it’s sturdy, sharp teeth eventually gnaw pieces and little shavings off the toy. These are microplastics and could be harmful if your dog swallows them.

Very sturdy chew toy
Color: Bacon
My Frenchy loves it! He’s not a large dog, but big for a French Bulldog. (32 lbs). He chews both ends, but prefers the snout. The eyes are cute, but began to peel off within the first week. I easily removed what was peeling. Half of the paint remained intact. When necessary, I will definitely replace it with the same toy.
