dogs and puppy exercises
The general rule is your puppy can exercise for 5 minute for each month they are old, twice a day, (your milage may vary.)
Your pup really shouldn't exercise or jump on hard surfaces such as cement until they are grown, due to growth plate issues. The larger the dog, the slower the plates join.
