Mark –
My Irish Setter “Formaggio” was diabetic and epileptic. She was on insulin and seizure meds in her old age.
My wife and I knew it was time when she became so weak that she could no longer walk. This was very difficult since we had her since she was a pup. She died at age 14 years. It was good that she was able to die at home.
I agree with you, this was a very difficult decision and one of the worst days of my life.
Our Setters have been a constant blessing in our lives with unfailing companionship – a true gift from above. Keep up the good work.
