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:
“Youth no less becomes
The light and careless livery that it wears
Than settled age his sables and his weeds,
Importing health and graveness.”
—William Shakespeare (1564–1616)
“At present the globe goes with a shattered constitution in its orbit.... No doubt the simple powers of nature, properly directed by man, would make it healthy and a paradise; as the laws of man’s own constitution but wait to be obeyed, to restore him to health and happiness.”
—Henry David Thoreau (1817–1862)
“We have two kinds of “conference.” One is that to which the office boy refers when he tells the applicant for a job that Mr. Blevitch is “in conference.” This means that Mr. Blevitch is in good health and reading the paper, but otherwise unoccupied. The other type of “conference” is bona fide in so far as it implies that three or four men are talking together in one room, and don’t want to be disturbed.”
—Robert Benchley (1889–1945)
