We have a Labrador, and she is honestly such an easy dog. I have heard that lab puppies stay puppy-ish for longer, and so some behaviours like chewing can take longer to grow out of for labs than other dogs - and that was certainly true for ddog1 - but she did grow up, and is now a very amenable dog. We can leave her at home alone if we go out, and she will just sleep until we get home.
If, for some reason, she doesn't get as much walking as is ideal, she is fine with that. As most labs are, she is very food-motivated, and that does make them easy to train - they will do a lot for a sniff of a gravy bone!
Ddog1 is a brown lab, and not the brightest bulb in the box, and I think this means she doesn't get bored easily, and is easily amused. Give her a glove to shred, and she is perfectly happy!
She is a real food thief, though - you really have to make sure all food is well out of reach! She will eat anything she can get hold of - including all sorts of poo, unfortunately. She has stolen anglers' sandwiches, when she got ahead of dh on a walk. He once left eight small steaks on the side, and she stole and ate three. He didn't learn his lesson, and a couple of weeks later, three salmon steaks went the same way! She once got into the cupboard where her big sack of food is kept, and ate 4.5kg before she was caught! She was a brown, furry barrel, and we didn't feed her for at least three days.
She is the most loving, cuddly dog, loves being with her people, and I cannot imagine life without at least one lab now!
They are prone to hip and knee issues - our other dog is a lab cross, and is going into the vet hospital next week for surgery to repair the worst of her knees - she's ruptured both knees' cruciate ligaments. The other will be done in about 6 weeks, and each is costing c£2.5k - so vet insurance is a must. If you get the dog from a breeder, always ask to see hip scores and eye scores (the lower, the better). Some do offer knee scores now too.
