Health
As with all created breeds, the Elo's small population size results in the risk of inbreeding and its after-effects of inbreeding depression, and frequent occurrence of hereditary diseases. There is a susceptibility to Distichia, in which corneal damage can occur. Part of the process of accepting a dog for breeding is an eye examination (for prevention of Distichia) and X-rays to avoid breeding dogs with hip dysplasia.
A genetic study has been done in Germany using the Elo, calculating the proportion of genes of the different founder breeds, of the inbreeding coefficient and relationship coefficients, and the percentage of stillborn puppies in litters. The study also found that all but 3.5% of the Elo were related to each other. The significant gene percentages of the Elo are 48% Eurasier, 23% Old English Sheepdog, 10% Chow chow. The inbreeding coefficient was found to be 12.04%.

Famous quotes containing the word health:
“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)
“Woman ... cannot be content with health and agility: she must make exorbitant efforts to appear something that never could exist without a diligent perversion of nature. Is it too much to ask that women be spared the daily struggle for superhuman beauty in order to offer it to the caresses of a subhumanly ugly mate?”
—Germaine Greer (b. 1939)
“Our young people are diseased with the theological problems of original sin, origin of evil, predestination, and the like. These never presented a practical difficulty to any man,—never darkened across any man’s road, who did not go out of his way to seek them. These are the soul’s mumps, and measles, and whooping- coughs, and those who have not caught them cannot describe their health or prescribe a cure. A simple mind will not know these enemies.”
—Ralph Waldo Emerson (1803–1882)
