BEST EVER!!!
We have a medium sized furbaby. He is the most gentle baby! Except with toys. He destroys everything he gets within 5 minutes. Even the aggressive chewer toys. He’s had these for a solid 24 hours. STILL INTACT!!! He’s loving them! Well, maybe he’s actually frustrated with them! Lol. He was able to stop it from squeaking… but he’s still having a ball playing with them. Not a single rip. I think we may need to put them up for a while to give his jaws and mind a break. BUY THEM NOW!!! Your baby will love them. And if they usually tear things up…. They will be able to enjoy this for a long time!!!

MUST HAVE!!! Dog is obsessed!!!
Color: Aqua
100 PLUS STARS!!! We have a very VERY active pup (6 yrs old 🤦‍♀️🤦‍♀️)… he has destroyed EVERYTHING we have ever given him. So I ordered this AND the replacement shell. He has chewed the ball extensively but it is in PERFECT shape, no need for the replacement one YET.. I can not rave about this enough - he LOVES it, we love watching him with it and he won’t let it out of his site at all!! If we touch it he gets upset.. so when we charge it, we put the shell back together and give him that.. which reminds me - make sure you have that screwed TIGHT.. somehow he was able to get it apart.. but once we started tightening it he hasn’t been able to.. thinking about it?? GET IT!! You won’t be disappointed and neither will your dog!!

An expensive ball to think about
Color: Aqua
Went with the foam ball because I have hopes that my dogs teeth will sink in enough to be satisfying without having to shred it like a tennis ball. So far, so good. I chose this one because the of the outer shell replacement possibility; assurance that 30 dollars towards a ball would have an extended life option for half the price if needed. It is slightly bigger than a tennis ball and big enough for my dog to be unable to get a strong clench and crush it. He does try though and it's holding up. All of the options and modes are great. However, I wish it acted more of a bait ball. Going through all three of the modes, I can't say any have sparked a wild chase. It will bounce intermittently or once touched. The intervals are long enough to lose my dogs interests. Short intervals make the ball the easy loser every time. Better on hardwood but pathetic on carpet. It will roll but not far or very fast. The only positives from this may be the battery conservation but when he stops playing with it, it is still rolling around the room. I think it takes 20-30 minutes of inactivity for sleep mode. With this, the charge will last about a day of play. It does charge quickly. It has passed the tough chewer test with one who can chew through "tuff" toys in no time but I wish it was more of a challenge. After telling my sister i purchased one, she said she would've given me hers because her dog had lost interest. Go with your hunch and find another game to invest in if you have trepidations of this being this case. I won't deduct anymore stars because the product is as advertised. Only one deducted for the price.

So far so good
Color: Aqua
For the past 2 years I’ve been looking for an interactive ball our dog won’t break within days. I appreciate that it’s all foam, without any ropes or plastic pieces he can chomp on. I don’t let him use it as a chew toy but after catching it he does like to chew on it for a little bit, and it’s held up nicely after a month. Would recommend
