Cherrybrook in the only one I've ever bought chews from online, because they sell the brand of Rawhides that WDJ recommends and I wanted to get some "better" ones for Jinj. They are good decent rawhides if you ask me, although even though Jinj loves just about every chew on this planet I was disappointed to find Enda hates them, oh well, so Jinjo gets a few more (but on a similar note, she also snubbed a Texas toothpick recently, guess she's not a chew fan then).
ETA: Wholesome hide is the brand name. But Cherrybrook also has other chews including antlers and Himalayan dog chews. Haven't priced compared those to other sites, I was just after the rawhides and they had another item I wanted that has been discontinued, plus $4.99 flat-rate shipping on all orders.
