The Tetraflex is made of the same unique matrial as the rest of the Everlasting range so it is very hardy. It measures a substantial 11cm across and is about 5cm thick. Fill it with treats and seal it with yummy paste and watch your dog have lots of fun.
It will take a fair amount of dry dog food so is an alternate way of feeding your dog a meal too.
It has an irregular shape which makes it wiggle while it rolls - dispensing treats or kibble as it goes.
