He is a BEAUTIFUL baby! I had a Sheltie "Lady Sarah" for 13 years....she was my very first baby. Honestly, after I lost her I didn't get another dog until my daughter got the one in my avatar. Obviously I have a VERY soft spot so I of course would get a second opinion. If it is "normal" for her fine, but just in case I would want to make sure it isn't an underlining problem. Good luck with your baby.
