Good article about how dogs got those teeth and jaws

Here is a snip...

Scientists say they have discovered why dogs love to eat meat and bones.

Ancient canines adopted pack-living about eight million years ago, to hunt larger prey, according to researchers.

The resulting evolution of their jaws gradually turned the ancestors of modern wolves, and ultimately our own pets, into "hypercarnivores".

Dr Joao Munoz-Doran presented the findings at the First Joint Congress for Evolutionary Biology in Ottawa, Canada.

He and his colleagues from the National University of Colombia have created a canine "family tree", piecing together the relationships between each of the more than 300 dog species.

Wish more such great articles would point out that their teeth shape and jaw capabilities (up & down only) haven't changed, i.e flattened/become elastic, respectively.  There's no gray area; room for any kind of debate when people can see with the naked eye.... that it is what it is.
