Severe Combined Immunodeficiency, SCID
SCID dogs cannot produce functional B-lymphocytes, the cells responsible for producing antibodies and long-term "memory" of infection, as well as T-lymphocytes, which can act to destroy infected cells as well as direct other immune cells to do their job. In the absence of a functional immune system, they are extremely susceptible to infections.

Signs and symptoms
Affected dogs are extremely susceptible to infections: bacterial, viral and parasitic. Affected puppies are often lethargic with poor growth.
Most SCID dogs are identified as puppies soon after weaning or when initially vaccinated with modified live products. -
Diagnosis
Genetic and laboratory testing along with clinical signs are used to diagnose this disease.
-
Treatment
Identifying the type of infection and giving appropriate medication is the only treatment currently available. Dogs with this condition often have a markedly shortened lifespan.

What to do if your dog is at risk
Actions
- Talk to your vet about your dog’s SCID result so you can work together to plan their ongoing care and monitoring.
- Work closely with your vet to prevent and manage infections through regular checkups, good hygiene, and prompt care if your dog becomes ill.
- Be cautious with activities that could cause injury or expose your dog to sources of infection, such as crowded dog parks or boarding facilities.
