Its a no contest here....Border Collie's

However I have to admit with the Border Collie its high maintenance no good IMO having one to do the things you want then loosing interest. They love both mental and physical stimulation.
All mine settle in the house (often being a coach potato)

However I have terriers too.....and our JRT could knock spots off the smartest BC

Im not keen on the everyday Labrador TBH, but I do like those that are the deep tan and I love Golden Retrievers
All the labs around here are extremely overweight...the owners fault not the dogs

I can see your dogs are fit and healthy, and I know of the training and work you do with them so I know that fit Labradors exist. But, for me, they are still too heavily built for what I like in a dog, thats just how Labradors are (or should be) made!

never had a lab,though i know they can be lovely dogs.theres only one breed for me,the border collie.Stunning in looks,highly intelligent,adaptable,willing to have a go at anything,no contest.

Hi Ive worked both breeds years ago in the beg/nov.
They are both capable ,but competitively the BC will give you the edge.

Okay, BC it is, now who's gonna tell the wife
