I am sorry to read this, GAD, but I know you made the right decision and that Guinness is at peace now. Still, it's hard to think that another one of NN's Newfs has left us. Hugs to your family.
I am just seeing this now...I don't know how I missed it...I am so incredibly sorry for the loss of Guinness...what a wonderful boy. As you have lost newfs before they leave such an incredible empty space where their big heads and bodies used to be...they and he will forever be loved and missed...big Hugs to you and your family!!
