Health
The breed has a reputation for being healthy with a long lifespan. Breeders have protected the gene pool, and direct in-line breeding has been prevented. Jack Russells can live anywhere from between 13 to 16 years on average given proper care. However certain lines have been noted for having specific health concerns, and therefore could occur in any line or generation because of recessive genes. These issues can include hereditary cataracts, ectopia lentis, congenital deafness, patellar luxation, ataxia, myasthenia gravis, Legg–Calvé–Perthes syndrome and von Willebrand disease.
Being a hunt-driven dog, the Jack Russell will usually pursue most creatures that it encounters. This includes the skunk, and the breed is prone to skunk toxic shock syndrome. The chemical in the skunk spray is absorbed by the dog and causes the red blood cells to undergo haemolysis, which can occasionally lead to fatal anemia and kidney failure. If sprayed underground, it can also cause chemical burning of the cornea. Treatments are available to flush the toxin out of the dog's system.

Famous quotes containing the word health:
“No one ever promised me it would be easy and it’s not. But I also get many rewards from seeing my children grow, make strong decisions for themselves, and set out on their own as independent, strong, likeable human beings. And I like who I am becoming, too. Having teenagers has made me more human, more flexible, more humble, more questioning—and, finally it’s given me a better sense of humor!”
—Anonymous Father. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 4 (1978)
“The sick man is taken away by the institution that takes charge not of the individual, but of his illness, an isolated object transformed or eliminated by technicians devoted to the defense of health the way others are attached to the defense of law and order or tidiness.”
—Michel de Certeau (1925–1986)
“However strongly they resist it, our kids have to learn that as adults we need the companionship and love of other adults. The more direct we are about our needs, the easier it may be for our children to accept those needs. Their jealousy may come from a fear that if we adults love each other we might not have any left for them. We have to let them know that it’s a different kind of love.”
—Ruth Davidson Bell. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 3 (1978)
