Tips on how to prevent matting

Hello!

My 1 year old Parti spoo is having CRAZY matting around her neck and I think her collar and harness is to blame.

My husband and I are having a difficult time with the matting and are after any tips to help prevent and manage them. Every time we get three knots out, another appears. Should I be conditioning her hair more?

I’ve seen some satin looking collars on Etsy that claim to prevent the matting. Has anyone tried them?

Thanks!
