I have a dog that I think is related to this animal. The resemblance was so remarkable it took me a second to determine whether or not to post here or on Potspoon! today! I refer to the dog as a Sabre-toothed chihuahua, and this is refered to as a sabre-toothed squirrel. Pretty similar in looks though I'll admit, Spencer does not have rodent teeth, he does have an under-bite with pretty large fangs.
See what I mean?
