When we look at the dog it is difficult to imagine how it has evolved over millions of years. Early mammals fed only on vegetation but in time meat eaters came about – they were able to survive by eating the vegetarians.
History takes us back to mouse sized , flesh eating mammals called Creodonts which lived at the same time as dinosaurs, 54 to 38 million years ago in the Eocene period. Believed to be tree and den dwellers, small with long backs, short legs, and long tails. Several characteristics of Miacis have been passed down to the dogs we know today.
