Starmark makes enrichment gear rather than soft toys: DuraFoam balls and discs for fetch, treat-dispensing puzzles that turn a meal into a job of work, the Everlasting chew system, and the Pro-Training clickers the brand's own training academy uses.
The distinction that trips people up is which toy takes which filling. The Everlasting Treat Ball, Bento Ball and Sprocket are built around Starmark's own Everlasting Treats, the domed chicken-flavoured dental chew sold separately in Small, Medium and Large. The Bob-A-Lot, Treat Dispensing Chew Ball, Tetraflex and Pickle Pocket take kibble or ordinary treats instead, so you can load them from the bag you already own. Buy the refill treats at the same time as an Everlasting toy and you will not be caught out.
Sizes follow the dog's weight, not the breed: Small is for dogs under 15 lb (about 7 kg), Medium under 40 lb (about 18 kg) and Large above that. Two more things worth knowing. The Tetraflex and the Swing & Fling DuraFoam Fetch Ball are interactive toys to use with your dog, not chew toys to leave down with a determined chewer, while the Everlasting balls and the Swing & Fling Chew Ball are the ones rated stronger than rubber. And the treats are not trivial in calories: the Everlasting Treat Ball listing puts a large treat at 295 calories, so count it against the day's food rather than on top of it.
