I've hit the age where I face this problem. Currently I'm down to three Hooligans ... Slider who's 10-1/2, Bruiser who will be 8 the first week in April, and Faith who's 5. I'm not sure if I want to have one or two dogs, only time will tell.
My current plans are to get older dogs, retired breeding dogs, etc. in the future WITH the agreement that if/when something happens to me, the breeder will take him back and either keep him or help find another home for him.
