When corgis have a longer coat length, they are referred to as a "Fluffy". The main reason that the fluffy coat corgis seem to be so rare to find and newer to existence is because fluffy coat corgis are against the original American Kennel Club (AKC) show standards.
This means that the fluffy coat corgis are considered a "fault" in the breed & show ring according to the AKC. The main reason for this is because their coat requires more maintenance and they are more difficult to keep clean than the "regular" standard coat corgis.
Corgis are a natural herding breed, so when the AKC set their standards back in 1934, when the Pembroke Welsh Corgi was officially recognized by the AKC, the longer & thicker coats were considered "undesirable" to those using the breed as working farm dogs.
THERE ARE ABSOLUTELY NO EXTRA HEALTH RISK ASSOCIATED WITH BREEDING FLUFFY COAT CORGIS. We have greatly evolved with society over time since 1934, and that is why the fluffy coat corgis are now becoming more popular. There are still some who will from upon even the responsible breeding of fluffy coat corgis, but we want to make it clear that at Curby's Corgis, we LOVE them and cannot get enough of them!
Fluffy Coat Corgis shed LESS than the Standard Coat Corgis, but we emphasized the word LESS than because while it is less than, THEY STILL DO SHED. Please do not get a fluffy coat corgi with the sole reason of thinking that you will not see or notice the hair (or what we refer to as "corgi glitter"), all over your house and clothing. You will still have to deal with the shedding!
