What it is
This is a congenital condition affecting the reproductive system where a dog's genetic sex (their chromosomes) does not match their physical gonads (internal reproductive organs like ovaries or testes) or external genitalia. This mismatch occurs during early development in the womb. Because it is inherited in an autosomal recessive pattern, a puppy must inherit the mutated gene from both parents to be affected.
How it presents
Owners typically notice signs as the dog reaches puberty or young adulthood, usually around 6 to 12 months of age. Affected dogs are infertile, may fail to show normal heat cycles, and can have unusual or ambiguous-looking external genitalia that are prone to chronic irritation or infections.
Treatment
The condition is treatable, typically requiring a one-time surgical removal of the malformed reproductive organs to prevent future tumors and infections. This surgery is a one-time expense that generally costs between 600 and 1800 EUR.
