I wouldn't care what you did. I WAS scheduled for knee surgery back in January (which a later cancelled) But I told everyone I won't see you for about 12 weeks. I gave them small bottles of shampoo and a pamphlet on getting the mats out. I saw a lot of hairy dogs but none that were so messy they had to be shaved off. I appreciate their loyalty very very much. But I also know that no one does as good a job as me (in this area) and if they did go to someone else, after one time, they'll be back to me. No bragging but some groomers are such slobs. Their shops are pig styes and the bathing with cheap shampoo and not cleaning the skin good enough is cheating the customer. They all charge around my rates, but I just raised every dog $5.
So If you LOVE his work, call him and tell him that. Maybe he will take in you as a private groom, just to make a little extra money without committing to a full days work. I love days like that. I don't answer the phone and I charge about $45 an hour
