A dachshund and Jack Russell terrier hybrid mix breed dog is commonly referred to as a Jackshund. These dogs grow to about 18 inches tall and weigh 15 to 28 pounds. Not all Jackhunds are the result of a 50-50 breeding between two purebred dogs.
Jackshunds have a life expectancy of 12 to 16 years and are family-friendly dogs. They are playful, affectionate, intelligent, trainable and dog-friendly. They make good watch dogs. The Jackshund's primary negative trait is its tendency to bark. Jackhunds have straight fur, and their ears are flappy. Jackshund dogs thrive in any type of climate, although they are uncommon and hard to find for sale.
