Dalmatian

General Health

Hereditary deafness is inherited as a polygenic trait and all Dalmatian bloodlines can pass along deafness to their offspring. Approximately eight percent of Dalmatians are born completely deaf and 22 to 24 percent are born with hearing in one ear only. All puppies are born with their ears closed. The ears should open by 12 to 16 days of age. In Dalmatians, the deafness is characterized by the permanent deterioration by the age of six weeks of the organs of Corti, the nerve cell group inside the cochlea that detect sound. Homemade hearing tests such as stomping on the floor, banging pans together are unreliable because the deaf puppy can feel the vibrations and often learns to adapt very well. The only reliable scientific test is the BAER (Brainstem Auditory Evoked Response). This is not available in all areas but is available at most large specialty practices and teaching hospitals at veterinary schools. It can be done any time after the puppy is five weeks old. Dogs that are used for breeding should have been tested for deafness, and many breeders test puppies before they are sent to their new homes.
Urolithiasis: The Dalmatian has a unique urinary tract system which makes them susceptible to the formation of urinary tract stones (Urolithiasis). The urine of a Dalmatian contains uric acid instead of urea or allantoin. Stones are formed from the salts of the uric acid. Large stones will lodge in the urethra; small stones also called gravel may pass with the urine. If the urinary tract becomes completely blocked and the condition is not treated promptly it will be fatal. Dalmatians must have adequate water at all times and dietary management with food that is not high in purines can be helpful. You can ask your vet to check your dogs’ urine at regular intervals for urate crystals. There is a lot of research being done in this area so new treatment and management protocols are always being developed. Discuss this with your vet.
Skin allergies: Many Dalmatians suffer from skin allergies. There are three main types of allergies: food-based allergies, which are treated by an elimination process of certain foods from the dog’s diet; contact allergies, caused by a reaction to a topical substance such as bedding, flea powders, dog shampoos, and other chemicals, and treated by removing the cause of the allergy; and inhalant allergies, caused by airborne allergens such as pollen, dust, and mildew. The medication for inhalant allergies depends on the severity of the allergy. It is important to note that ear infections often accompany inhalant allergies.
Hip dysplasia: Hip dyplasia is a heritable condition in which the femur doesn’t fit snugly into the pelvic socket of the hip joint. Hip dysplasia can exist with or without clinical signs. Some dogs exhibit pain and lameness on one or both rear legs. As the dog ages, arthritis can develop. X-ray screening for hip dysplasia is done by the Orthopedic Foundation for Animals or the University of Pennsylvania Hip Improvement Program. Dogs with hip dysplasia should not be bred. Ask the breeder for proof that the parents have been tested for hip dysplasia and found to be free of problems.
Iris Sphincter Dysplasia: an inherited ocular disorder that can cause sensitivity to bright light, poor night vision, partial or total blindness, and cataracts. At this point it is not frequently seen in Dalmatians although some studies argue that it is often overlooked. The condition and its treatments are being studied.
Seizures are also present in all breeds. Seizures usually require careful monitoring of medication. A dog that is affected with seizures will need to stay on medication his whole life and should not be bred.
Hypothyroidism seems to be on the rise in all dogs. Some holistic practioners feel it is due to improper diet and overkill with vaccinations. Some signs of hypothyroidism include lethargy, excess shedding, dull coat, overweight, skin problems, reproductive difficulties, etc.
