Can someone tell me the most important things to look for when looking for a Border Collie Puppy?

supreme human physical fitness and a spare 4 to 6 hours to exercise and stimulate him per day (wont be a pup for long). 

LOL & for the puppy parents eye, hip & DNA tested(eye test must be within a year to be current), good temperaments & depending on what you want your BC for ie pet/obedience/agility etc depends on where you should look(ie KC/ISDS, ISDS or KC only)

Hi,
Do you want it for a pet or working dog.
Does it have to be a tiny pup?
If it is for a pet only. Join and email me.
Regards
Denese

You've forgotten the eyes up your backside and the ability to read the mind of a dog that is smart enough to outwit a large proportion of the human and canine population, they are also VERY good at training you and sometimes people don't even notice that they are doing it LOL LOL. I know a few like that and find it very funny watching the owners running around after their dog which is apparently stupid and untrainable.... ;-)

ditto Colliemad. Macey my B/c used to own me as a pup but now at the grand age of 15 she has now took over again, hearing & seeing what she wants too. But I love her so much, she knows this and does stuff cos she can...
