My adult dogs really like this treat feeder and love working to get the goodies out of it! It’s held up well over many months despite their biting and gnawing on it, so a good purchase overall. It’s also different than the usual Kongs so adds some variety to their feeder puzzle repertoire to keep up the diversity of mental stimulation.

Not tough enough

Color: Red

Finding durable chew toys for my pup is a challenge. When I placed a medium dog biscuit inside this, it kept him busy for awhile. But then I noticed small pieces of the toy around the house and discovered that he had managed to shred it. I've since discarded it and continue to search for toys guaranteed to be safe for "aggressive chewers".

Loves it

Color: Red

He loves this thing. He was able to chew some pieces off, but otherwise it is very durable. He likes to bounce it around to get treats out of the middle and the holes on the sides is where additional treats can be placed. It washes up fairly easy . Perfect size for my 40 pound dog

Keeps dogs busy.

Color: Orange

The dogs love this ball. They are afraid when it vibrates but as soon as it jumps and moves around, they are on it. They will play with it for quite awhile. Charge lasts for a long time. Very durable. This dog can tear anything apart but it's still in one piece.
