I bought a cd a couple of years ago and watched it at least 20 times before I dared. lol It's been almost 3 years and I think I do okay. Just got a compliment from the vet today as a matter of fact. lol
I say to myself, "it will grow back". lol.
I like doing it as it's a bonding time as well. I enjoy it. I do take them to get their nails and glands done tho. The place I used to take Hot Rod to does nails several times a week and glands for like $3 a dog-total!!! Can't beat that and a ton of people go for it as well.
Good luck, I think you will enjoy it.
