I cannot give these to my labrador cross because she chomps her way through them too quickly and they cost a lot, but for my 5 month old sheepdog puppy, they are absolutely perfect. He can gnaw on one of these over a period of days and days. Perfect for when you need to get on with something or just have a sit down for an hour. Then I swap it for a toy or treat and put it away for the next day. Excellent value and no mess.
