The pictures are as if they were taken of “Baxter” my first scottie who died of a lymphoma at 8. I now have a wheaton scottie, “Duffee”, who is 10 and has recently gone deaf, but doesn’t appear to be botherd by his deafness and is very healthy otherwise. Last year I inheritated my Mother’s 10 year old blue healer “Daux” who is blind, he compleatly lost his sight about 18 months ago but copes very well and he also does not seem to be bothered by his loss of sight. Unlike Duffee, Daux is very intelligent and a problem solver.
Now I know why your nic is also is duffee, named after your dog. :)
