Dogs love it, hard to open and close
Size: Large, Color: Pink, Size: Large, Color: Pink
My dogs love this toy. It keeps them entertained a long time. Great calming toy for when you leave the house. Only issues is it is very hard to open and close. One of mine I had three people try to open and after fighting with it for about an hour I finally got it opened. Got 2, one a blue and pink one for each of my dogs. The blue is easier than the pink but still hard to do. Just not as bad. Can't close the pink all the way because it is so hard to close. The dog that uses it has trouble getting the stuff out of it. But it doesn't stop her from trying for hours to do so. Does get some teeth marks on it as well if they are aggressive chewer. Tried multiple eatable lubricating substances to try to make it easier but so far nothing fully worked. Aloe Vera has worked the best so far, but not great.

Good in theory, but didn’t fully deliver
Size: Large, Color: Green, Size: Large, Color: Green
My dog falls right on the size cutoff between the small and large Pupsicle. I initially ordered the large since he’s a strong chewer, but he had trouble getting everything out, so I ended up trying the small as well. There are definitely some positives. I think the design is better than a Kong. It stays upright, which makes it less messy. I also really like the mold for making the inserts, instead of having to fill the toy itself and freeze it. That said, there are two major design issues that impacted my experience. First, the all-rubber construction creates a lot of friction when screwing the bottom into the base, especially after repeated use. It gradually became harder to open, to the point where I was using coconut or avocado oil to try to loosen the threads. At one point I even needed a wrench and pliers just to get a better grip. Second, while it’s marketed as dishwasher safe (which I was excited about for cleaning), it seems to dry out the rubber and makes the threading issue worse over time. Unfortunately, mine is now permanently stuck shut and no longer usable. Overall, I like the concept, but the durability and usability issues make this a 3-star product for me. I’d recommend it with caution, especially if you plan to wash it frequently.

Cute toy and well made
These are very cute and so far my dog has not destroyed them and he’s a very aggressive chewer. They are great quality. The colors are vibrant. Rocky loves the squeaker. They're light weight and the perfect size . He enjoys playing with them. We like to take them when he’s not looking and throw them to watch him go fetch them.

Love these!!
My dog absolutely loves these toys!! I’m grateful they don’t tear up easily because he’s really harsh on toys. Love that you can add treats or a water bottle to get more engagement and enjoyment. This by far is one of my dogs favorite toys. Great value for the money and great quality.
