A great enrichment toy to keep your dog occupied
Style: Fox
Do you have a small furry gremlin disguised as a dog in your life that needs entertaining while you work? Get yourself one of these!
PROS
- it keeps a smart dog occupied for anywhere between 10-20 minutes
- if keeps a less than smart dog occupied a lot longer
- you can fit quite a lot of treats of different sizes in there
- you can throw it in the washing machine when it gets too dirty
- also doubles as a tug of war toy
CONS
- it gets dirty fast
- if you have a heavy chewer they'll rip it up and render it useless pretty quickly
- it squeaks (good for dog not for human)
This is one of my girls favourite toys, even now that she's a bit older and doesn't need constant stimulation she still enjoys running around with it and digging the treats out.

Dog loved it.
Style: Frog
Dog loved it, squeaker lasted about 5 minutes, which is about normal for any toy I’ve given her.

Frustrating and Not Durable
Style: Turtle
My Foxhound /Beagle mix had this toy torn in several places within minutes. He loves his toys, but this one seemed to frustrate him and me. The small slits are too tight for anything but kibble. The large pouch is too deep for treats, and would send kibble flying as soon as he shook it. Anything larger would get stuck! The pouch tore at the seams as soon as my dog tried to pull out a Milkbone. Only small treats would fit in the slits, and he’d lose interest with them. The squeaker was useless due to the large size and hardness of the head. The weight and size of the head and the length of the toy might be a problem for smaller dogs. This toy was returned.

GSP Approved!
Style: Frog
Our GSP loves this! It's only keeps her busy for a few minutes, but then she carries around for an hour. The pockets are a great size for training treats and the Velcro has held up well despite repeated daily use!
