Perfect
Color: Blue
I am fostering a Husky/Black and Tan Coon dog. We have had her since early February. She has chewed up a lot of my shoes. She destroyed my other dogs stuffed squeaky toys. So I decided to buy her this ball. She reminds me of Linus from Charlie Brown. She wakes up with this ball and falls asleep with it. I’ve not had another shoe fatality. This ball is her most loved possession. It is pretty tough. Now She did kill the squeaker within the first few hours (which trust me I am GOOD with that! I’ve never put treats in it. The rope is still attached. After this review I am going to buy her another as a back up!

Great for large breeds!
Color: Red, Color: Red
I have trouble finding chew toys that are both durable and affordable, but this one has been a great find! It’s perfect for larger breeds because it’s heavy-duty and made from thick, sturdy material. Unlike some rubber toys, it doesn’t have that strong rubbery odor, which I really appreciate.
Since it’s made from a single material, it’s also incredibly easy to clean—just wipe it down or give it a quick spray. Another bonus is that my dog’s teeth don’t squeak against it as much as they do with some other toys. Overall, I’m very impressed with the quality and durability. It’s an excellent value for the money, and I would definitely recommend it!

Durable and Dogs love it
Color: Red, Color: Red
Great for aggressive chewers. I have Large dogs that rip through almost every toy. They love to play tug a war with this but mostly just lay in the yard and chewed on it. Its still holding up strong. It is made od a heavy duty rubber type material. It has no odor. The color is bright red and has not faded as of yet. It appears to be safe since they have yet to chew any places pieces off. We take it camping or on trips so portability is nice. Its definately worth the money. I would recommend.

Hefty but good quality!
Color: Red
It's hefty! I bought this for my 70lb Dutch Sheperd/Malinois mix because she, as the breeds are, is extremely active and loves to play tug of war. I read the reviews and knew the bone was noted to be heavy but bought it anyway. It was a little bulky for her at first and she let it lie for a couple of months but was picking it up today. I will get use out it with her as she continues to grow but definitely not for smaller dogs. It's still a good, sturdy product!
