I have only taken Cohen to a groomer twice and it is a lady who just runs it out of her house. She only does an okay job, but my breeder recommended her to me which is why I took him there. I didn't tip her...but I was confused about it. I knew that I tip my hairdresser, but I wasn't sure it was custom to tip dog groomers or not. I'll def tip her next time and I feel awful now.
