re: Old dog. At what point you say good bye?

I feel for you man...

I've got a 15 y.o. female yellow that means more to me than some humans...not only my retired hunting companion, but she was our first child when my wife and I thought we couldn't have kids...

She's arthritic, but still gets around...stumbles a lot and sometimes falls down, but she's still happy to be with us...

My vet(an HRC trainer) once told me, the time is when they no longer wag their tail or pick their head up to greet you as you walk by...

My 14yo son is going to be hit the hardest as he claims her as his own...she sleeps in his bed nightly and he waits on her hand and foot...if she's having a hard time going up or down the stairs to go outside, he will carry her...if she's having a bad day and needs help onto the sofa, he is there to help her...

May God bless you and guide your decision in this matter...
