hiya,
Well my lot - now 10 months, and 9 half months, get the usual 45 min walk on the evenings, sometimes a 15-20 min walk before work.
Depending on whho's home early or what set of parents are over, they will also get a off lead run about 30-45mins, It just depends on what we are up to and the time we have, they always get walked everday. If we cant get out for long walks they will get alot more in house clicker or obedience training to make them tired.
Some weekends they get between 5 and 9 miles walking, combined on and off lead. Satursday walk was for 9miles, should have been 7 but last 2 bwe got lost, hahaha!!
