My Irish Wolfhound/Rottie mix (Sasha) is impossible to groom at home. I have electric shavers as well as manual shears that I use on our Lhasa, but every time I turn it on Sasha becomes so anxious she hides, and has peed on the floor on a few occasions. Clipping her nails is a nightmare as well. She's terrified of the grinder and the clippers. When she needs groomed I take her to professionals, who have a really tough time holding down a terrified 92 lb dog. Has anyone else had similar problems? Any tips on how to calm her down so I could groom her at home?
