Make sure you see the dam with her pups and don't be afraid to ask questions. Dog or Bitch This is personal preference.

A Labrador puppy should not be over exercised, in fact when you first acquire your pup the exercise he gets from playing with you and his visits to the garden for toileting will be adequate. From six months your puppy can have twenty minutes free running and half an hour walking on the lead daily. When your dog gets to eighteen months old, he will be able to endure as much exercise as you are able to give him. Bitches will grow to 21.5-22 inches at the withers. Dogs will also be heavier than bitches.
