What causes the ridge on Rhodesian Ridgebacks?

What causes the ridge on Rhodesian Ridgebacks?

The ridge of Rhodesian Ridgebacks is caused by a mutation resulting in duplication of a length of DNA coding for three growth factor genes. This mutation, which has an autosomal dominant pattern of inheritance also causes dermoid sinuses.

Why do some Rhodesian Ridgebacks not have a ridge?

Homozygous dogs — those with two copies of the gene — will never produce ridgeless. That’s because, when it comes time for homozgyous Ridgebacks to donate one of their two genes to offspring, all they have to pass on is a ridge gene.

What is the average cost of a Rhodesian Ridgeback?

$1,700 to $2,500
The typical price of a Rhodesian Ridgeback puppy is $1,700 to $2,500, with an average of $2,100. Rhodesian ridgeback price is normally based on the breeder, bloodline, kennel club registration and appearance of the dog.

How do I know if my dog has a dermoid sinus?

Symptoms of Dermoid Sinus in Dogs

  1. Can be recognized on your puppy by an opening along his back with hair in a swirl pattern (can be found as early as 3-5 weeks)
  2. You may feel a tube or rope under his skin under the opening on his back.
  3. Mild discharge without any other symptoms.
  4. Infection.
  5. Abscesses.
  6. Neurological concerns.

Can you breed a Ridgeless Ridgeback?

Ridgeless Rhodesian Ridgebacks don’t carry the ridge gene at all, and cannot produce ridged offspring any more than a Chesapeake Bay retriever or Chihuahua can. Ridgeback breeders who are interested in ridge inheritance often forget that not having a ridge is the normative state in dogs.

Can Rhodesian Ridgebacks be left alone?

We would never recommend leaving your Rhodesian Ridgeback alone for more than four hours. Because they form such strong ties with their families, you’ll need to gradually train them that it is OK to be alone.

What is dermoid sinus in Rhodesian Ridgebacks?

The dermoid sinus in Rhodesian ridgebacks is a congenital defect caused by incomplete separation between the skin and spinal cord, after closure of the embryonic neural tube (16). Several modes of inheritance have been proposed, but the exact mechanism is not established (1,16,17).
