Congenital Ectodermal Dysplasia
A genetic disorder affecting hair, teeth, and skin development, responsible for the hairless trait in certain dog breeds.
Detailed Description
Congenital ectodermal dysplasia is caused by mutations affecting the development of ectodermal tissues, resulting in partial or complete hairlessness, missing or malformed teeth, and sometimes abnormal sweat gland function. While not a disease per se, it predisposes affected dogs to secondary issues such as dental problems and skin infections.
Common Symptoms
- Partial or complete hairlessness
- Missing or malformed teeth
- Dry or sensitive skin
- Prone to sunburn
- Skin infections
Management Options
- Dental care (cleaning, extractions)
- Skin care (moisturizers, sunscreen, infection management)
- Protective clothing for sun exposure
Frequently Asked Questions
