I've only tried a mobile groomer once and had horrible results. She butchered my poor Tucker so bad that I had to take him to the vet to get stitches afterward. She also took the entire first layer of skin off of his little backside. I had heard great things about her but made the mistake of letting her groom him without my supervision. My lesson learned was never use a groomer for the first time without watching them. She is the reason why I still drive 45 minutes to take my boys to Pet Paradise (the best groomers ever
)
I'm sure that she is not representative of all mobile groomers and hopefully others on here have had good experiences. I would definately keep an eye on her for the first time though, good references are not enough.
BTW: Those in the Nashville area, stay away from Bark & Paw, Grrrr
