This is one of my older pictures. I drew it about 18 years before I took up drawing again. Nadine was a Great Dane that lived with me for about six years. I had to re-home her when I got pregnant because she attacked the crying doll I was hoding in my arms and jumped over a baby gate to do so. The baby doll didn't appreciate the bite in the stomach, and the dog trainer and I thought my little daughter wouldn't appreciate that either.
Anyway, here's my stab at a paw and a nose.
