I have a Brittany that is 14 months. I tried to take it easy walking and running him when he was that young. I used the 5 min per month of age rule, so at 4 months, I would walk him 20 minutes twice a day. At 14 months, he did 80 miles last month.
Those 2 walks weren't enough to tire him out, so I had to do other things. A make a flirt pole out of a piece of PVC, some rope, and some baseball bat grip tape. I tied a fuzzy dog critter toy on the end of the rope. I could knock tire him out to where he would be flat on the floor in under 10 minutes with that thing.
I found this on the web. This is basically what I did, but I didn't use any washers. I just tied knots on both ends, and instead of a ball I used a furry critter toy.
