Respiratory Effected Genes in a Man's Best Friend

For a lot of us pet lovers, our little pups are our best friends.  Some of us own puppies with smushed faces, such as Bulldogs, Pugs, and Boston Terriers, who sometimes have trouble breathing.  However, their breathing troubles may not only be caused from their skull shape but from the recently discovered gene affecting respiratory systems.

A study was done on the Norwich Terrier dog breed, a dog with a perfectly protruding nose that is known to have trouble breathing.  A total of 401 Norwich Terriers that all had history of wheezing were studied and were found to have the same gene in their DNA.  It was the gene variant ADAMTS3 that was found in these Norwich Terriers, and had been previously linked to the cause of swelling around airways causing a respiratory tract disorder.

Out of the 401 DNA sampled dogs, 33% of them had 2 copies of the ADAMTS3 gene and displayed worse  respiratory symptoms.  The dogs that obtained one gene still experienced symptoms, but not as bad.

Perhaps breeders can utilize this discovery to help determine whether or not they want to breed certain dogs.  It can assist in giving future pet owners healthier puppies and less problems that would involve less future trips to the veterinarian.

Troubled Breathing Dogs

The gene ADAMTS3 has been associated with the swelling of the airways inside dogs noses. This has been identified as a respiratory tract disorder and share the same genes between different breeds of dogs. Many of them had copies of this gene leading to a worse performance of breathing than other dogs with the lack of this mutated gene. The mutation affects the swelling in the nostrils as well as around the dogs lungs. The dogs thought to have these breathing problems are the dogs with smooched faces. This is now looked at to not be the only reason these dogs are having the effect of breathing problems. The breed “Norwich terriers” have breathing problems but their snouts are normal and in no way an effect of this problem. Jeffery Schoenebeck stated, “This is the first evidence to show that its not just all about skull size”. Bulldogs have this problem as well with having a hard time to breath. I think this is great research because this can lead dog breeders to breed healthier puppies and make them have a better life. Breeders can use a genetic test to keep the dogs with the ADAMTS3 gene from reproducing and passing it along to more dogs. Many of these dogs with their breathing problems come to a pretty high cost due to the treatments they will eventually need at some time in their lives. Genetic tests for your own dogs might come into play and be the next big thing!
