My dog is high strung and can be challenging to groom. In the past, other groomers have missed spots underneath because he is so active. Other groomers have also complained. A bit annoying since they're working with animals. What do you expect?!
I have never had complaints at Petco. One groomer/tech even wrote us a very nice note about his experience. Apparently, he really bonded with her during the experience! When we go to Petco, this anxious furry boy drags us to get inside. What more of an endorsement can you ask for?
