Luckily yorkie hair never stops growing. I really understand your upset...it's much like having a child with beautiful hair and then having to trust a new hairdresser with it. I'm really a HUGE advocate for "word of mouth". It would have been a good idea to have reshown the groomer the pic you'd originally showed her and expressed your disappointment. It's ok to be honest. I feel she needed to take responsibility for a job well distroyed. If ever you were to play dress up with your baby...NOW would be the time. Don't cry and be sad...please. Get him a nice new outfit lol!!!
My sister lives in Toronto (I'm in Montreal...). She also has a yorkie, but her baby doesn't have a lot of hair and she HAS to keep her hair short short short. Not sure if her groomer is a good one but I'll ask her where she goes, but she told me a while back that she has 2 neighbors on her street that have yorkies...they have to groom them somewhere... I speak to her each and every Sunday (today!). I can find out the information if you like. There are a TON of conscientious yorkie people in Toronto FOR SURE!
Keep in touch...
