I have 2 labs, both black ( so less tumbleweed than a yellow). Lab 1 has a stunning working line pedigree , lots of FTCh’s, on both sides. He was my very first dog as an adult. I waited a long time , having met his dam, for her to have her litter. Lab 2 was bred by a gamekeeper, no known pedigree, no health tests, just a long history of healthy dogs from that stock.
They are pets, never had to ‘work’ a day in their lives. We put in the work training and they do like a job - carrying the leads home from a walk , or bringing the newspaper upstairs, or indeed my slippers to the last place I will look. We do play hide and seek, search for toys, put the toys back in the basket . We use food toys and slow feeders.
They are very chilled as they get appropriate exercise; they are both a good weight and size, as is typical of working stock; they have both clearly understood everything that is expected of a lab - sociable, affable, greedy, gentle , willing to please. They will run around with my teenage nephew and a ball, and they would saunter slowly next to my aging Dad.
I really really struggle with all the working/ show line stuff that is spouted, as my two continue to be a joy to live with, purely as pets. The effort you put in is repaid by what you get out.
And in answer to one question you asked OP, they sleep pretty much where they like, which is generally somewhere close to us. How close depends on how warm it is.
