Pronunciation: [ jak rat ta•ree•er]

The Jack Rat Terrier is a small hybrid dog whose parent breeds are the Jack Russell Terrier and the Rat Terrier. These hybrids were one of the many designer dogs that came out of the 1990s. While the American Kennel Club (AKC) doesn't recognize the Jack Russel as a breed by name, other kennel clubs do. (The Rat Terrier is recognized by the AKC.) Regardless, the Jack Rat Terrier is a crossbreed and is therefore not recognized by the AKC nor any other formal kennel club.

Jack-rat Terrier Breed Description

There is not a lot of Jack Rat Terrier information available. The two breeds that are crossed to produce this hybrid dog are somewhat similar, however. They are little dogs but are not unlike tightly wound springs. They enjoy both mental and physical challenges during their many daily hours of activity.

This mixed breed is highly intelligent. Because one of the parent breeds is a Rat Terrier, there is a fair chance that they will be more emotionally intelligent. This helps when it comes to training; experienced handlers are best. They are great hunting dogs and can also be used for therapy and related work.

While these dogs are hugely loyal, they will demand a lot too. They tend to get easily excited, and perhaps one of the more common complaints is about their jumping. Also, if you want a lapdog that you can leave behind while you go to work or go out at night, this is not the dog.

Jack Rat Terriers require a lot of daily outdoor activity. Failing to do so will prompt them to bark a lot, be destructive and to jump like crazy. A lot of shared activity every day and for as long as you can manage is best. At night, these dogs will unwind by just being flat-out lazy — which is a very good sign.

Jack-rat Terrier Temperament

The Jack Russell Rat Terrier mix temperament is not an easy one to tame or train. These highly energetic, extremely curious and somewhat unstoppable little hybrid dogs are fearless adventurers who will challenge you every step of the way.

Trying to tire out this dog is recommended only for true athletes. If you love to run daily or take miles-long walks, this dog will happily be by your side the whole time. Once home after a long day, they will also be happy to rest on your lap and sleep by your side so they can get ready for the next day. These dogs are extremely loyal, and they will be far more manageable for those who have very active lifestyles.

Training these dogs may not be easy. While you do need to be firm and patient, you also need to keep them engaged as they become easily bored. They are remarkably energetic, and they need a lot of proper and consistent behavioral training from very early on to curb their constant jumping and other bad habits that are easily excited. They must be socialized with any non-canine pets you have in the house. With strangers, they tend to be wary and will take their time getting to know a new person before being comfortable with them.

Jack-rat Terrier Health

There are not too many health concerns with this mixed breed dog, but they also don't seem to gain much from the hybrid vigor that benefits many crossbreeds. Perhaps the biggest concern is self-induced injuries. One of the parent breeds, the Rat Terrier, is so well-known for such semi-intentional "accidents" that the AKC breed standard allows for scars and broken teeth. Whether your Jack Rat Terrier inherits this trait can't be controlled and will have to be borne out in action to see if he has such behavior.

Other health concerns that may affect your dog include:

  • Mange
  • Allergies
  • Deafness
  • Eye ailments
  • Hip concerns
  • Incorrect bites
  • Knee problems

These hyper, hybrid dogs tend to have a life span ranging from 14 to 18 years.
