A 2024 UK study found a life expectancy of 13.2 years for the Dalmatian compared to an average of 12.7 for purebreeds and 12 for
crossbreeds. In their late teens, both males and females may suffer from
bone spurs and
arthritic conditions. Autoimmune thyroiditis may be a relatively common condition for the breed, affecting 11.6% of dogs.
Dermatological conditions The breed is predisposed the following dermatological conditions:
atopic dermatitis, solar dermatosis, and
squamous cell carcinoma.
Deafness A study in the UK found 18.4% of tested Dalmatians to be deaf in either one or both ears. This study also found no association between coat colour and deafness. A Swiss study looking at 575 dogs from 33 different families found 16.5% of Dalmatians to be deaf in either one or both ears. A German study of 1899 dogs from 169 different kennels found 19.6% of Dalmatians to be deaf in one or both ears. This study concluded that genes other than those responsible for colouring significantly contributed to deafness. A US study found 25.7% of Dalmatians to be deaf in one or both ears. This study found that the evidence of a single gene being responsible for deafness to be unlikely. Researchers now know deafness in albino and
piebald animals is caused by the absence of mature
melanocytes in the inner ear. This may affect one or both ears. Typically, only dogs with bilateral hearing are bred, although those with unilateral hearing, and even dogs with bilateral
deafness, make fine pets with appropriate training. It has been proved that it is the inheritance of the extreme piebald gene that causes blue eyes. It is therefore frowned upon to breed from blue-eyed Dalmatians even if they are fully hearing. In the UK, blue eyes are considered a breed standard fault so blue-eyed Dalmatians will not be rewarded in the show ring.
Skeletal conditions A North American study of veterinary hospital records found that of over 9,000 Dalmatians, 1.36% had
hip dysplasia compared to the overall rate of 3.52%.
Hyperuricemia Dalmatians, like
humans, can suffer from
hyperuricemia. Dalmatians' livers have trouble breaking down
uric acid, which can build up in the
blood serum (
hyperuricemia) causing
gout. Uric acid can also be excreted in high concentration into the
urine, causing
kidney stones and
bladder stones. These conditions are most likely to occur in middle-aged males. Males over ten are prone to kidney stones and should have their calcium intake reduced or be given preventive medication. To reduce the risk of gout and stones, owners should carefully limit the intake of
purines by avoiding giving their dogs food containing organ meats,
animal byproducts, or other high-purine ingredients. Hyperuricemia in Dalmatians responds to treatment with
orgotein, the veterinary formulation of the antioxidant enzyme
superoxide dismutase.
Dalmatian-Pointer Backcross Project Hyperuricemia in Dalmatians (as in all breeds) is inherited, but unlike other breeds, the normal gene for a uric acid transporter that allows for uric acid to enter liver cells and be subsequently broken down is not present in the breed's gene pool. Therefore, there is no possibility of eliminating hyperuricemia among pure-bred Dalmatians. The only possible solution to this problem must then be crossing Dalmatians with other breeds to reintroduce the normal uric acid transporter gene. This led to the foundation of the Dalmatian-Pointer Backcross Project, which aims to reintroduce the normal uric acid transporter gene into the Dalmatian breed. The backcross used a single
English Pointer; subsequent breedings have all been to purebred Dalmatians. This project was started in 1973 by Dr. Robert Schaible. The first cross (F1) hybrids did not resemble Dalmatians very closely. The F1s were then crossed back to purebreds. This breeding produced puppies of closer resemblance to the pure Dalmatian. By the fifth generation in 1981, they resembled purebreds so much, Dr. Schaible convinced the AKC to allow two of the hybrids to be registered as purebreds. Then AKC President William F. Stifel stated, "If there is a logical, scientific way to correct genetic health problems associated with certain breed traits and still preserve the integrity of the breed standard, it is incumbent upon the American Kennel Club to lead the way." The Dalmatian Club of America's (DCA) board of directors supported this decision; however, it quickly became highly controversial among the club members. A vote by DCA members opposed the registration of the hybrids, causing the AKC to ban registration to any of the dog's offspring. At the annual general meeting of the DCA in May 2006, the backcross issue was discussed again by club members. In June of the same year, DCA members were presented with an opportunity to vote on whether to reopen the discussion of the Dalmatian Backcross Project. The results of this ballot were nearly 2:1 in favor of re-examining support of the project by the DCA. This has begun with the publication of articles presenting more information both in support of and questioning the need for this project. In July 2011, the AKC agreed to allow registration of backcrossed Dalmatians. In 2010, the UK Kennel Club registered a backcrossed Dalmatian called Ch.
Fiacre's First and Foremost. Several restrictions were imposed on the dog. Although the dog is at least 13 generations removed from the original Pointer cross, its
F1 to F3 progeny will be marked on registration certificates with asterisks (which "indicate impure or unverified breeding") no progeny will be eligible to be exported as pedigrees for the next five years, and all have to be health tested. UK Dalmatian breed clubs have objected to the decision by the Kennel Club. Although LUA Dalmatians will not develop the urinary stones, they can still develop other types.
Dalmatian Heritage Project The Dalmatian Heritage Project began in 2005. The goal of the project is to preserve and improve the Dalmatian breed by breeding friendly and confident parent dogs with normal urinary metabolism and bilateral hearing. All puppies in the Heritage Project are descendants of Dr. Robert Schaible's parent line. == History ==
