I don't bring mine to the groomers anymore, I just do it myself after some grooming horror. I used to tip 15%-20% out of the bill depending on how happy I am with the way they treat my dog. One groomer charged like $60 which is a high price and I only tipped $5 because I wasn't happy with the groom. I save so much from doing my own grooming and I don't have to worry about how they treat my dog while I am not there, if they are being gentle, if they accidentally nicked him etc etc. From the money I save, I buy high quality shampoo, conditioner for him
But, the bugger won't let me cut his nails so I do bring him to a groomer about 25mins away every 2-3 weeks and they are good with him. She does his nails and express his anal glands. Tip included I pay $10. I would trust this particular groomer with my dog because she is so nice and her skills are good but if I can do it myself and enjoy spending that time bathing, grooming him, I'd rather do it myself and the best is, I know little bugger prefers me doing it.
