Would you trust this person to groom?

sorry no i wouldn't trust a 15yr old to groom my dogs. does she know how to handle all dogs? some dogs with under coats can't be cut like normal dogs. I know you said you have a yorkie i am just wondering I have two terriers and their groomer said that most terriers they have groomed hate to have their feet touched as mine do would she know what to do? unless i knew her or had a friend use her then no. good luck
