Meet The Volkosoby,

and from what I have read if you are a criminal,

this is a close as you would like to be to one, they are a highly-trained wolf-dog hybrid, created to inherit the size and strength of wolves, but retain an obedient and friendly attitude toward humans that they do not perceive as threats, for years this goal has eluded dog breeders,

 but scientists and animal experts at Russia’s Prem Institute of Internal Troops finally made a breakthrough in the year 2000, the key to their success was Naida, an usually sociable Caspian Sea Wolf who got along great with humans, before you rush out to buy a Volkosoby, the Russian Military uses them as border guards, but does not sell wolf-dogs, instead, it only leases them to domestic security organizations, under very strict conditions, but what makes the volkosoby hybrids so valuable to the Russian Military is their ability to outperform any other dog species, for example, while German Shepherds would take about four minutes to sniff out a hiding criminal, the wolf-dogs were able to do it in just 15 to 20 seconds, they have a heightened sense of smell (six times sharper than a dog), their grip is unusually strong, allowing them to bite through protective layers of plastic and felt, and they can withstand extreme temperatures, they also display great stamina and mental stability, they can track their prey continuously for up to two days without tiring, in combat situations, whereas a dog will bite an aggressor’s arm and maintain its bite, a Volkosoby will also go for the arm initially, but will eventually focus its attention on a more vulnerable area, like the groin or neck, during a gunfight, the Volkosoby will not react to gunfire, but instead focus on its task,

 a note to criminals on Russia's borders, remember the Volkosoby you are tangling with has brothers, lots of them!
