I normally wouldn't say shave down a yorkie - but if the matts are that bad...in my opinion...yes. It would be pretty painful to get them out if they're close to the skin and really bad.....Sometimes it's better to go ahead and her hair and start fresh and try to keep up with grooming so this doesn't happen again.
Wearing clothes can really cause matts....When my girls wear clothes I use a finishing spray on them before I dress them to cut down on the tangles |
