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:
“A woman’s health is her capital.”
—Harriet Beecher Stowe (1811–1896)
“To speak or do anything that shall concern mankind, one must speak and act as if well, or from that grain of health which he has left.”
—Henry David Thoreau (1817–1862)
“I am astonished at the singular pertinacity and endurance of our lives. The miracle is, that what is is, when it is so difficult, if not impossible, for anything else to be; that we walk on in our particular paths so far, before we fall on death and fate, merely because we must walk in some path; that every man can get a living, and so few can do anything more. So much only can I accomplish ere health and strength are gone, and yet this suffices.”
—Henry David Thoreau (1817–1862)
