I have a cattle dog that belongs to a common subspecies of domestic dog—canis manducatione—the chewing dog. He does have a small underbite, which makes me think part of his problem is improper occlusion. I will be fixing that problem in the near future, but for the moment (and for the last 10 months) I have been dealing with a super chewer. That brings up the topic of chew toys.
The last 30 years of dog training lore revolves around the connection between wolves and dogs. You can buy 100 books that prattle about dogs being descended from wolves; animals that voluntarily live in groups, called packs. This perspective invariably assumes that dogs are likewise “pack animals”. The underlying implication is that dogs possess the same wolf-like ability to live in harmony with their own kind.
