Long haired guinea pigs- how much of the chin hair to cut?

[EffOneGPs]

Got a question on long haired guinea pigs- when giving them haircuts (especially now given the high temperatures we're facing), how much of the hair on a guinea pig's chin should be cut?

There's a couple of examples below from the The North East Guinea Pig Groomer @ Facebook which give some guidance but is that the maximum one should go?
I ask because I can't remember reading somewhere that the chin/cheek hair or "mutton chops / beards" shouldn't be cut too short as this is a guinea pig's "radar" to guide it around solid objects at night and cutting it too short could result in a guinea pig risking injury through collisions into objects it couldn't sense.

Thanks!

I don't have an answer but I love the photos! I haven't cut my two piggies' mutton chops very much but not for that reason.

that looks like a fab hair cut.its the whiskers that guinea pigs use to navigate,so its important you do not cut these.your piggies will be sooo cool now !

I take off the mutton chops but am very careful not to cut the whiskers or eyebrows. If short-haired piggies manage without mutton chops then I can't see how long-haired ones need them. Here's Louise after her first trim. All her whiskers are on her ginger face; eyebrow whiskers are probably there somewhere...?

Great job
As said above, avoid the whiskers.
Beautiful piggies by the way

I wish they were mine, but sadly not- they're one of many model guinea pigs showcased by this talented groomer!
Thanks for the advice BTW, it really helps this prospective new owner!

Just thought when looking at this post again- if you accidentally trim a guinea pig's whiskers, do they grow back?

I don't know but I would think so as in nature they would wear away as they brushed against things so they would need to grow back. And it's just a type of hair after all.

Yes they do grow back, and actually quite quickly.
Oreo often used to power groom her beloved Eddi, and that sometimes included nibbling his whiskers off.
Eddi never seemed bothered by it.
