So, I have taken up biking with the dogs and they love it!! We went out last night for the first time having them both hooked up together (I had taken them out separately about a week ago to see how they would do since Spencer usually lunges at bikes), I thought for sure they would have me in a ditch somewhere but they did great. Tonight, I brought my GPS with me to see how far we actually went. I took them for a 5km run in just under 34 minutes and that counted the time for 5 stops for them. Spencer thinks that he should just pull me along the whole time, at parts of it, I don't even have to petal, actually I have to use my break to slow him down (he goes a little too fast for Sydney). Being just on his collar I tried not to let him too much. I am really thinking of getting him a pulling harness and just letting him go at it. It is definitely a great workout for them, I am thinking about starting to go out before work with them, if we could do 5km in 30 minutes, I would only have to be out there by about 5:00am. Plus, at that time there would be less worry about cars. I wish I could video tape them doing it, they do so awesome and look so cute.
