We have an 18 mo golden that is very active. He has begun running with my husband. My husband usually takes him out 2-3 times a week and varies the running medium. Sometimes they run through the neighborhood to the school and then sanders will run (and run and run) off lead on the grassy field while my husband runs about 4 miles around the track. Sanders does not run the 4 at the field but by the time they get back home, it is easily four miles. Other times, my husband will take him on trails and he will run for about 45 minutes. Other forms of exercise for sanders includes agility classes one night a week and daily swimming.
My question is how much is too much and is it too early to be running like this? Is running up to 6 miles at a time healthy for him? His lineage is clear of HD and elbows but i want to be sure we are not setting him up for issues later on in life. thanks for any help/advice given.
