Watch the start of Marley and Me times that by 10.
your clothes, furniture, car will become embedded with fur, no vacuum cleaner has been invented that can clear the fur, daily hoovering is essential and lots of sellotape to remove hairs from clothes.
they need a LOT of exercise once past adolescence I’d say 4 miles a day everyday as a minimum
expect to spend the first two years training them
they are clever, loyal and fabulous watchdogs who bond closely with their families and will pine if dumped into a kennels ( 3 reputable kennel owners I know all said they are warier of a Lab than almost any other breed due to being bitten or witnessing aggressive behaviour because the dog is deeply emotionally traumatised by separation). If you get a lab, either socialise the dog with a friend or family member who the dog likes and they can look after the dog when you toddle off on holiday or just accept no foreign holiday travel for 10 - 14 years.
they are so clever they are capable of working out how to open kitchen cupboards that do not have handles and scoffing whatever they find inside, then reward you with bodily eruptions all over your carpet. They are dustbins, food centric and will eat and eat and eat until they are literally sick. You have to harden your heart to brown eyed starvation look. Training a lab around food is really important, sitting nicely and staying when bowl put down, teaching them not to scoff things that fall on the floor, not to touch plates ( as a kid I was given a slice of cheesecake and didn’t like it, hid it behind the sofa, for hours everyone was wondering why the dog was dribbling and staring transfixed at the back of the sofa …. The next day the cheesecake was discovered fully intact…. )
they love water are great swimmers but take ages to dry, you will end up with more dog towels than ones for the humans in your household.
I am a dedicated dog lover and grew up with them, I choose not to have a Labrador due to the exercise requirements and the fact they are bonkers for two years (have found spaniels to be a better household fit). As with most dogs, you get out what you put in. I am heartily sick of everyone talking about what fabulous family dogs they are and merrily forget the many labs that are overweight, under stimulated and locked up in houses day in and day out. They are an active breed and deserve the respect of exercise and dedication to training. Oh and don’t buy from back yard breeders, they need to be hip scored.
