Another bad groomer story

I'm so sorry this happened to your baby. Personally, I've been so afraid to take Yoshi in for a grooming after the last groomer chopped off his top knot. It's taken MONTHS to grow back & it's still not long enough to keep out of his eyes all the way. I tried to do his ears by myself the other week & it was a disaster! I did a horrible job!
Can anyone reccommend a GOOD grooming video? The ones I've seen on YouTube aren't great & I'd love to learn the correct way to keep Yoshi from looking like a ragdoll in between searching for a good groomer.
