Exercise regime

Hello,

Can anyone recommend how much exercise I should begin with my 13-week-old Siberian Husky bitch and how I should build this up over time to full long walks and runs?

Thank you,

Too much, too young?

A fortnight ago I acquired my first puppy for 15 years, having had a series of adolescent rehomes, and am interested in current thinking regarding exercise levels. He is 16 weeks old ( a post Christmas rehome) and is going out and about for socialisation as he has missed out on this so far, but how much, if any, free running should he have?
The net seems to suggest exercise should be five minutes for every month ie 20 minutes, but I'm not sure if this is up-to-date thinking, ot if this is free running or on-lead, which is obviously more controlled.
At the moment he is usually doing about 20 minutes on-lead once a day with one of my geriatric dogs who is kindly showing him how to behave politely when out, and obviously having play/training sessions several times a day at home, inside at present due to the weather, but I have a fairly small garden anyway. Sometimes I have been replacing the lead walk with a similar amount of time off-lead on suitable occasions where he can interact with other dogs known to me.
He is a fairly small leggy Border Collie (I hope he will grow!) and is destined to be an agility dog, though obviously won't be starting training on agility equipment until he is a year old.
Current thinking on this subject would be appreciated.
