I've had dogs my whole life growing up until I moved into my own place. We had a Rottweiler when I was very young, and then when I got older we got a lab mix from a friend and a terrier mix stray. Now my family has a lab-pit-bulldog-who knows mix and a toy poodle and they are best friends. I've been walking the dogs and feeding them my whole life, and once I got older began dog-sitting and dog-walking for neighbors and friends. I have great experience with large dogs, but preferred trained dogs that don't pull too hard. I have experience with crate training (if that's what you prefer) but any way works!
