So you've realized its not as easy as it may look. We often get people bringing their dogs in for us to fix after they've attempted it at home. Just have the groomer shave her short, like a #7-#10, she won't have that cute fluffy look, but it will last a few months so you don't have to spend $50 per month. I only groom Sydney (my parent's schnauzer) every 2-3 months, I clip her short so it lasts longer (she does get baths in between of course). Or if you want to attempt this again, get a pair of clippers with interchangeable blades, not ones that have different size plastic comb attachments. I bet she still looks cute, I think we need some new Callie pics anyway.
