[4] Others believe that the dermoid sinus condition is more appropriately characterized as polygenic, involving multiple genes.
[5] In any case, because of the genetic nature of this potentially dangerous condition, most breeders and veterinarians advise against breeding animals that have a dermoid sinus, or have a parent that is known to carry the gene.
[5] Surgical excision is the only remedy for this condition, with veterinary surgeons removing abnormal tissue and closing any connections to the spine, In some cases, regrowth of the sinus occurs.
Other, more basic tests, such as a complete blood count, biochemical profile, and urinalysis can be performed to determine if infection or other problems exist.
Computed tomography scans and magnetic resonance imaging may be undertaken to determine if neurological signs exist as a result of the sinus.
