The Coton is in general a healthy breed. However, there are still some health issues as there are in all breeds. The most serious issues are heart problems, liver shunts, back (disc) problems, and eye problems. Luckily, these are still relatively uncommon in the breed. The small gene pool of this breed is owing to its near extinction. Due to inbreeding by disreputable breeders there is an increased incidence of disease. The smaller the gene pool, the more likely a breed is to have genetic abnormalities.
