Advice wanted: my mum has a rescue dog with curly hair that easily knots and mats. He's a very nervous dog when it comes to brushes, baths, scissors, clippers, etc. Groomers refuse to help as he can get nippy when scared and stressed. My mum cuts the knots out herself with lots of coaxing but he needs a proper trim. The vet said they would trim him under anesthesia at the extreme minimum cost of £160 a time. Can you help please? We desperately need to find a groomer experienced with nervous, nippy dogs.
