Lynsey - you may recall we had a similar thread before on do you or don't you trim your dogs' whiskers. I am a snipper
It does not hurt them. They are not used in the same way as cat's whiskers and so if you don't like them, cut them off - Jessie will be fine. Jasp and Bud have always had their's snipped - I prefer the smooth look
You need to be confident snipping tho and Jessie needs to keep still or you could catch her lips or face - and oddly, they don't like that
You can either generally snip flat to the face or do each individually.. I do a bit of both doing the thicker ones individually with the pooints to try and get them very short so you can't see them.
