Dentley's Compressed Rawhide Bones www.petsmart.com - $5.49 Product Description: Compressed Rawhide is the best kind for hard chewers, because its densely packed layers offer a good chewing challenge. Your dog will enjoy the all-natural munchy goodness with no artificial additives. Pressed rawhide lasts 3 to 5 times longer than regular rawhide and won't break apart. RattyRat's Review: Never buy anything with rawhide in it for your rats. The rawhide will bloat in their stomach and make them sick or worse. No rawhide!
