How long do Jack Russell terrier mix live?
We have a Welshie/Jack Russell mix who is 15 and going strong,
despite spending the first seven years of her life churning out
pups in a notorious puppy mill. Aside from a few stray white hairs,
she can still pass for half her age. She runs like a gazelle,
dances, etc. Long may she continue in good health. Nothing is
written in stone when it comes to dogs' longevity, especially
terriers.
