No Mess, Lots of Fun!
Size: Large, Color: 5 Pack
My dog absolutely loves these toys! The squeakers and crinkle sounds keep him entertained for hours, and I appreciate that they have no stuffing—so no messy cleanup when he plays a little rough. The variety pack is great because it gives him different animals to choose from, and the toys are surprisingly durable even with lots of chewing.
They’re lightweight, easy for him to carry around, and perfect for playtime or keeping him busy when I’m working. Definitely a great value for the price, and I’ll be buying again when he wears them out. Highly recommend!

Great
Size: Large, Color: 5 Pack
These are big deal toys for our dogs. Use them when have to go out for a whole day. Have bought three sets over about two years. Takes them a several days to gut and get to the squeaker. They keep the skin around for months if we let them.

Great Interactive Toy for My Dogs
Color: Fox-Crocodile
I have four dogs with different personalities and energy levels, and these toys have been a fun addition to our home. The two dogs in the photos were the first to test them, and they immediately started sniffing, searching, and working to get the treats hidden inside.
The toys are soft, well-made, and provide great mental stimulation. I like that they keep my dogs entertained while encouraging them to use their noses and problem-solving skills. The treat compartments work best with small training treats, and the toys have held up well during regular play.
Overall, this has been a great enrichment toy for my pack. If you have small or medium-sized dogs that enjoy treat puzzles and interactive toys, I would definitely recommend giving these a try.
The two pups in the photos approved them right away, and the other two quickly joined the fun!

Great toy for our mouthy chewing very active dog - he loves it and so do we!
Color: Fox-Crocodile
Great buy!
Dog is very mouthy, so got this to try to focus chewing on a toy rather than me, and he loves it.
Pockets are a little small for many treats, but they do hold very small ones tucked into each triangle - (16 small treats total between the two toys), and rolls up with a strong velcro which holds pretty well. Dog will forcefully wedge his nose into the roll trying to get to the treats and it doesn't unroll until he works it over.
Wasn't positive how well it would hold up - he is a very mouthy puppy who is very strong and likes to shred, but out of all the toys, it has held up some of the best (on par with the kong toys so far) where others are not faring so well. He has pulled and tugged at the eyes, feet and ears repeatedly, and they are still firmly attached and no fraying on the treat spots at this time. He throws this thing around playing by himself and aside from being dirty now being one of his favorite toys, it looks as good as new. The only problem we have had is one of the squeakers no longer squeaks as he seems to have managed to remove that part of the noisemaker - but no holes, no rips, no shreds, nothing else showing wear and tear.
He has even used it for tug of war on occasion and though we didn't let that last too long, it showed no signs of tearing or ripping from that either.
