I had a terrible experience with a mobile groomer once and I never will again! She had one of those small motor homes that park in your driveway. My dog looked great but then I noticed under her top knot were these little spots that looked like tiny bugs or something. I took out the top knot and there was a gash in the top of her head and the spots were scabs or dried blood. I don't ever remember being so furious! I understand accidents happen but at least tell me so I can take care of it!
