Not very durable
Size: Small - 2 Count (Pack of 1)
I purchased some of these balls a while back and had forgotten how quickly my yorkie puppy was able to destroy them.. I recently ordered some more bc I saw them on sale. I now have another yorkie pup that also loves to play ball. They actually play ball with each other. Within 24 hrs, the balls are fraying and they are getting choked on the fuzzy s off the balls. I'm not going to bother to return 3 2pks bc they were so cheap. Now I know why.

This ball seems to be a counterfeit.
Size: Large - 2 Count ( Pack of 1), Size: Large - 2 Count ( Pack of 1)
This ball seems to be a counterfeit and if it is not, it was made not to be played with by animal or human. In a review I just read, Iduna had posted this: Iduna 1.0 out of 5 stars Only for the most docile of play Reviewed in the United States on March 6, 2024 Size: Large - Pack of 2Verified Purchase I thought it was great that these came in all sizes and bought the large for an urban dog park hoping it would not go through the slats of the fence and bought these as sort of a test before I bought the launcher. While the sizing was great unfortunately each one lasted a little more than half an hour. The rubber sphere part is constructed of two halves and I don't know if there's any sort of sealant between those two halves or if it's just held together by the thin tennis ball type cover but some bouncing off of the turf covered concrete and dog play upon retrieval caused the two rubber halves to separate and a few more tosses led it to quit bouncing and sort of squished together when the dogs grabbed it. That caused the thin tennis ball type material to fray and all was lost. This post was more than true without any exaggeration. Our dog fetched it in the house and tore it up within 5 mins. The original Chuckit launcher and ball was our first purchase thinking that these would be great balls to replace the Launcher ball which actually lasted our dog about 3 months of constant play and grinding on it (He loved that thing). This one came apart very easily as you can see, but the smell of the broken rubber was extremely solvent smelling (like toluene) of which I have good experience with chemicals like it from the industry in which I worked. Industrial solvents are definitely bad for our pets and that is the smell that comes out of this broken ball even at a distance. It filled our kitchen with the stench. I find this rather suspect when the description says: "this toy is designed with an extra-thick natural rubber core". In any case, the ball fell apart quickly and it is not like the launcher ball at all. I coach tennis and a real tennis ball would be better for our dog than this thing. Broken tennis balls don't smell like that at all and they last much longer and cost the same amount for 3 or 4 vs 2.

Defective seam
Size: Large - 2 Count ( Pack of 1), Size: Large - 2 Count ( Pack of 1)
My dogs love these, defective or not. I have purchased the two ball set this is the 3rd and last time. Each set has had one ball with a defective seam on interior rubber ball which means it splits open on the first squeeze from the dogs.
