Shows wear quickly
Color: Multicolor/Sheep & Cow, Size: Medium
These are cute but not holding up as well as I had hoped. Quality is ok and the Velcro has held up great. The fabric just isn’t as good as it could be. They are much larger than expected.

Great toy!
Size: Medium, Style: Ultra Tug
We have a 1 yr old rescue (German shepherd mix) and she didnt really know how to play with humans, she was scared of everything. We got this toy to help us teach her how to play fetch and tug of war and it really helped her come out of her shell. She loves this toy! It is very durable and fun to throw. Just enough rope to tug with her and doesn't come apart like other rope material. We got medium size and prob buy another one.

Durable and fun
Size: Medium, Style: Ultra Tug, Size: Medium, Style: Ultra Tug
This is a cool toy. My dog took to it right away. It tosses great. I like that you can play a little tugging along with fetch. We mainly use it outdoors. It feels very strong and durable. For size reference my dog is a mini golden doodle and weighs about 30lbs.

Durable
Size: Small, Style: Ultra Duo Tug
Well, our dogs didn't end up playing tug with each other, but they love the toy anyway and it still looks pretty good after a month. That doesn't sound like much, but they both love to chew and destroy rubber and they're ridiculously good at it. They also really like chewing the strap between the two balls, which is still in surprisingly good condition. Most "indestructible" toys are toast within the hour. Well worth the money. Plus, the unpredictable bounce when thrown keeps the dogs busy.

Good quality ball for large dog, easy to clean
Size: Large, Style: Ultra Tug
It’s challenging to review this because I bought it for my son’s dog, and it doesn’t interest him at all, even though he likes and plays with regular balls. The ball appears to be good quality, which is typical for this brand. He likes to play tug of war, so I thought the combination with a ball would be a hit. The strap looks durable, so time will tell if he develops an interest in playing with this at some point. The ball is hard rubber and fairly heavy, so it should hold up to an aggressive chewer. It doesn’t squeak or make any other noise. It bounces unpredictably and erratically because of the attached strap. Both the strap and ball are easy to clean with soap and water.
