I feel your pain Mark.
I was just talking to my older sister yesterday about this.
50 years ago at the age of 16 I was with our 16 year old Boxer, Maximillian the Great the Third, when we had to make that decision.
My dad showed Max for a while. He was the most beautiful Boxer I have ever seen and my best friend growing up.
I have never personally owned a dog since that sad day.
Mark,
We will be at the River house this weekend. Give me a call if you are at the Willow pad.
