I am new in labs, I have 4, 1 is about 14 months, 2 are 9 months and 1 is 6 months.
About excercise them, I am not talking about jogging, I think that hearts their bones.
What I am talking about is, walking them and a lot of swimming, they look very good, very strong and the breeder that sold them to me said she had never seen such a strong labs, she is asking for my advice, imagine, sorry, so my question is:
Exercise is important for growing puppies. Swimming, retrieving and long walks (age appropriate distances of course)help your lab to develop properly and to stay in shape. Same for people! I swear if it weren't for my dogs I would have even more middle age spread!!
Swimming is wonderful exercise. Walking is good too. My dogs love to play in deep dirt or sand. Retrieve in it gives them great exercise and strength.
Keeps muscles healthy!!
I take mine for tramps in the fields & woods near my house. Obviously I don't go over rough terrain, so they have the option of taking the "easy" route. If they're tired, they can walk with me, or if they're needing more exercise, there's always chances to run around like a fool, go through the heavy terrain (which they do) as well as swim as we walk back to a river.
I generally start pitching fetch toys closer to the end of the walk, so they don't wear out and still have the whole walk to go through.
