Can anyone please tell me the minimum amount of exersize needed for a GSD?

Hi guest..
What age ?? puppies need very little excercise, by that I mean until they are about 4 months old playing in the garden is fine.Then a ten minute walk, then at 8months ish increase it to 25mins.No real excercise until at least a year old and been hip scored.Never throw things in the air otherwise as the dog jumps for the toy it will casuse stress on the joints.As a gsd doesn't stop growing until it is about 18 months it's very unwise to over excercise.
Make sure you go to a 'nice' training group for socialisation as soon as vaccinations have kicked in.It's much easier to train a puppy than a huge dog that wants to pull you about everywhere.
Hope this help you. :)
