Good size but pee leaks through :(
Size: X-Large, Style: 40 Count, Size: X-Large, Style: 40 Count
I have a 13-14 year old dog who is starting to have very frequent accidents in the house despite us taking her outside every couple of hours, she just drinks too much water which doesn’t mesh well with her weakening, old bladder. She tends to have an accident in two areas (the kitchen and right by the front door hallway) so we decided to buy some puppy pads to minimize the mess & aid in cleanup since clearly taking her outside every couple frequently isn’t helping reduce accidents. We chose these because of the size & price, which are both fantastic compared to others. It perfectly fits the two areas she tends to go so we only need to use one per area and to our surprise, she still remembers how to use puppy pads so she adapted quickly.
But unfortunately, these don’t hold all of her pee as they are very thin. I just cleaned up the kitchen puppy pad and saw moisture under the pee spot on the pad. So while it does dramatically reduce how much we need to clean up (we were using one paper towel roll every 3 days just for her accidents), we still need to wipe down the floor with pet accident cleaning spray & mop. It’s not that big of an issue but it is still a bit frustrating that they don’t hold fluid well.
So keep that in mind if you decide to order these, that you might still need to wipe down the floor under where your puppy/dog pees. We’ll be trying a different brand when we run out of these to see if that’s any better.

Great buy
Size: Giant, Style: 40 Count
These pads are great. Absorbent and leak resistant.
Very roomy for my chihuahua to turn in her inconsistent circles before and durable enough for her to "dig" after without ripping or bunching up.

Brilliant fun for dog, except for...
I have a 3yo German Shepherd Dog (GSD) and he can be very hard on toys. On days 1 and 2 he had such fun and we laughed at his good times!
Then...Day 3...cue the Jaws Music... While I was away for 10 minutes, he dismantled the ball into tiny pieces! Even so, the ball continued to light up, make sounds and entertain my GSD!!
Coolest dog toy ever!
If you have a heavy chewer....watch out!
Otherwise, I highly recommend!!

Disappointing Dog Toy – Short-Lived and Ineffective
I purchased this dog toy hoping it would keep my dog entertained and engaged, but unfortunately, it has been a huge disappointment. The first one I received only worked for about an hour before completely stopping. I decided to give it another chance and ordered a second one, hoping it was just a fluke. Unfortunately, the second one lasted even shorter—only 30 minutes—before completely ceasing to function.
It no longer vibrates, rotates, or interacts in any way. Even when fully charged, the toy barely lights up and doesn’t do anything useful. This is a terrible product, and I’m genuinely shocked by the positive reviews. Save your money—this toy is not worth it.

My dog loves it
My Aussie loves it and he is a tough chewer as well, so it goes great with his hyper reactive personality. Durability could have been a little better, sometimes I have to take it apart and make sure it’s still in a good position because my dog will pick it up and drop it. With no cushion it did start malfunctioning at about 2 weeks. However, it does still work fine and he loves it even without the movement.
Note if you put it in a sock to protect it, my dog goes dangerous and held the sock and created a slingshot lol.
