Yes, in the NE and into Eastern canada the 'yotes do have wolf DNA--this variant is much more common than the coy-dog. They are much larger than the southern and SW native coyotes. They have moved into areas that used to have wolf populations. The animals responsible for the death of the hiker on Cape Breton were DNA examined and found to have this difference as well. They have spread rapidly over the last 30 years and are becoming a growing problem. They are even using the ravines to make their way right into the city of Toronto. They are bold and highly adaptable, and will take on large dogs. A Golden breeder friend in Ohio lost a bitch this winter who was attacked INSIDE their dog yard. Her throat was crushed.
