I'm always thinking about what kind of dog I'll want went I'm a senior and can't handle a large and energetic dog. Maybe a basset hound?
I have been thinking about this aswell, and still have not come up with a breed, maybe a Border Terrier.

Definitly in the future i will have another Border Collie, in about 2-3 years time depending on litters and breeding with the breeder i have chosen (Not wiping out rescues if the "Right" dog comes up in rescue sure). Then there is my Boxer, who was going to be my next dog (Maybe it will happen) and also i am determined to get my Staffordshire Bull Terrier.

I would like to have another Rotti X with another herding dog . And i would "Love" a Borzoi and an afghan.

Hmmm i think i have the next 50 years or so worked out, dog wise.
