Hi, my 2 year old husky, Loki, and I have been working on running with a bicycle since I got him in July.  We started with little half mile jaunts and now are increasing to the 5-10 mile range.  He loves to run/pull the bicycle.  He used to run beside me until he broke the bicycle leash pulling too hard on it lol.  So currently he runs on a regular leash in front of me and off to the side a little, which allows me to monitor him more closely.  We are working on  learning commands etc on our local bike path and coming along nicely.  The problem we are having is that if we run bare footed (Musher's secret) his nails file down to the quick and bleed.  If we wear shoes (CE Canine Experience brand)  his foot rolls over when he runs so we have to take them off not too long after we begin.  I wondered if he was pushing too hard to keep up, so I have been exclusively coasting for the last few weeks and the problems remain.  His shoes were sized at the pet store, though I am not ruling out that they could be on the big side.  Loki always is excited for the bike and generally returns to home with plenty of energy after a ride, doing yard laps after we are done followed by a quick nap. I want him to be able to have a good and safe biking experience.  Any and all suggestions are strongly encouraged and greatly appreciated.  Thank you in advance for your help!

Look into mushing booties from dogbooties.com or Mountain Ridge should be mtnridge.com - Mountain Ridge makes a tough bootie. Be prepared to replace them but they allow flexibility of the foot.

Should edit both make "tougher" booties but I've personally tried the mountain ridge tough booties and loved them. Though I dont use pavement much they worked for a gravel race I once did.
