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.

Great chew toy, long lasting
Color: Bacon
This chew toy has been amazing. We have had it for 2 months with 2 dogs chewy on it and it is still going strong. We have a large Golden who chews on everything and and German Shepherd. Big dogs who chew aggressively. Very impressed! Would definitely buy again!
