From what I have researched there is absolutely no proof that the gene carries health issues with it. It's speculated but no proof. I don't know really know though, it's hard to trust much on the Internet lol.
I will say my parents bought 2 pure bred welsh corgis from extremely reputable breeder. One of the 2 had long fur, a thicker tongue and ears than standard, fatter legs and paws etc. The breeder called him a freak mutation she had never seen in a corgi. My parents didn't care and bought him anyway. He just died a few weeks ago. He was 14 years old (the exact life span for a corgi), he never had any health probelms his entire life until he reached his old age. He died a few months after the other corgi we got passed as well. Both had long healthy lives with no problems at all. That to me says a mutation doesn't mean they are not worth getting. Sebastian was just as happy, healthy and well mannered as Maggie was. |
