Updated title: Not for a power chewer
Size: Dog Rope Toy - M
Update: I had to cut the ball off the same day I wrote this review. Two days later, the yellow rope was totally unraveled and I had to throw it away. She got maybe 3 days of play with this toy. Do not buy this toy if you have a larger dog that chews a lot. I will say our dog loved this toy the moment she started playing with it. But the toy doesn't last long with our superchewer. I was hoping to use it for some games of tug, and while we're at it get her teeth cleaned by the spikey red ball. The listing includes "large" dogs. My large dog (11 m/o Bernese puppy) had this toy broken within the first 10 minutes. The red pieces are a pretty lightweight plastic that she just broke apart completely, specifically the bone on the "handle". The ball is lasting a little longer, but she put a hole in it. We will probably need to cut the ball off as well because she'll chew it up and swallow it if we're not careful, and then she'll need (another) surgery. The positive is that she loves chewing on rope and the rope pieces seem pretty sturdy. We still play tug with the ropes, but this one I will probably just give to her as a chew toy. We found a more durable ball on a rope toy at Target for a little bit less.

This toy will not hold up
Size: Dog Rope Toy - M
I bought this for my heavy chewer. The plastic pieces lasted about 15 minutes. She is an Italian Mastiff, but she is only 7 months old. I expected more from a toy that was rated as 'tough'.

Best and toughest dog toy on the market 4 all breeds and sized dogs
Size: Large, Size: Large
Now i know this doesnt appear to be good based off the photos but hear me out. My pitbull (and any pitbull owner will most likley know the same struggle with chew toys) is an extrememly tough ans agressive chewer! Every toy i would purchase for him from rubber ones to rope ones, enormous raw hides, oversized balls thinking it would be hard for him to bite believing that would increase its life, it did not. None of the toys lasted for more than a few HOURS!!! And that was when he was being easy with them! I was on the line of stopping biying him toys and letting him just chew sticks, but then one day in a coversation with my plumber and familt friend he mentioned trying kong brand dog toys. I didnt have anything to lose besides more money and an hour of entertainment for my dog so i decided to try them. I bought 3 different kong brand toys. A tug of war one that was rope with kong rubber grip handled ends, a weird ball like toy that was able to add peanut butter in a small hole and this toy. Amazed the tug of war toy(handles only) even though fairly thin lasted over 3 days!! And thats huuuuge for him with toys. Then the little peanut butter ball thing lasted about a week! I was sold. But then he finally got to try this ball with tug of war handles that contains a tennis ball when it finally is destroyed as a bonus toy and it even squeeks and the swueeker was even guarded by the rubber so it wasnt crushed immediatley! Now afyer seeing the picture of said ball it is destroyed now but it lasted many tug of wars with him and him gnawinf on it for hours every day. The kicker is i bought it roughly around september 16th, it is now JANUARY 21st!!!!! The ball has now lasted him approximately 4months 5days! Thats an insane increse of chew life for any pitbull especially mine. And it ximes in 2 sizes. The large is a little bigger than a large cantelope or slightly smaller than a basketball. And they have a smaller version for small breed heavy chewers!! I couldnt be more pleased with this purchase and will definatley be ordering 3 more ASAP considering his prob only has another week or 2 left. The only negatives are 1, when they do chew off the handles tou cant play tug of war any more and 2 that when they finally get into the main cavity where they can actually start chewing off little bits of it they emd up all over the place, bunchesmof little rubber nubs but its easy to clean. So if you have an extremely heavy chewer as i do and are looking for a toy that is worth the money and will last your dog a good time and that they will love(my dogs fav toy hes ever had) and u want it to squeek and have a bonus toy inside of it to hold them over til the next one arrives when they ruin it, then trust me! BUY KONG CHEW TOYS. specifically THIS TOY!! Best dog brand and toy on the market. Ajd its safe and if im not mistaken harmful chemical and bpa free so ur pups can chew safely. And it cleans their teeth as a bonus because of the tough rubber!! Its so worth it. only recommendation. Buy atleast 1 large 1 and one small one if u have a medium-large dog. If their small then probably only the small one or any other kong toy. If they're light chewers u probably will mever have to buy another chew toy again! Its that good and strong yet still flexible enough to squeek it!! Hope this review helps you and encourages u to buy this toy and brand over any other!!!
