Assuming a dog has gluteal sulci, is there a word for the fluffy hair that covers them?

Picture a fluffy dog, eg., a Golden Retriever. Rear view. Long fluffy, sometimes billowy hair slightly lower and to either side of tail.

I call them his “curtains.”

Not that left-field of a question, because there is a word for the longish fur off the back of a dog’s front “forearms” (I believe only the front, but I’m not sure): “feathers.”

ETA: I am not a dog. Therefore, Plato is correct.

I’ve heard “feathers”.

Of course, that may be used by 5 people, but I have heard it.

Yes, feathers. That’s the term for the longer fur on the rear of the legs and also the tail.

Yup. Feathers. I think it’s used by more than 5 people. There are three right here in this thread. So far.

ETA: The word I haven’t heard is “gluteal sulci.”

Couldn’t find a clear cite, but this Dummies page on canine anatomy uses the term.

That’s the only term I’ve ever encountered, either.

In the Aussie world, they also called “pants”.

That longish hair on the lower portions of the legs and on the tail, I have always seen referred to as “feather” (a collective noun in singular form). I’ve never seen it used this way in the plural form “feathers”.

The same word is also used for the long shaggy hair on the lower legs of some breeds of horses, but not for the long hair that all horses have on their manes and tails.

On Scotties, it’s referred to as the kilt.

on my dogs it’s called pantaloons…just because I like that. (all three of my dogs have flippy-up tails and pantaloons)

I think ‘feather’ or ‘feathers’ is the most common word, but I’ve often referred to them as britches or pantaloons. I once had an Aussie whose legs changed color right where the feathers stopped, so we called them her hot pants.
