So I have a converted kid trailer for cargo, but I am planning some camping trips via bike and wanted to bring my dogs. I was thinking of using a trailer frame with the plastic kennels bolted on to it to use for the dogs. One dog (boxer/coonhound mix, 65lbs) likes to run along side the bike on his lead, but the other (rat terrier, 20lbs) hates to. I was thinking that the bigger kennel bolted onto the trailer base with a smaller kennel bolted to the top of that would be a good solution for both dogs when they get tired and overnights. Has anyone done this before? How do you travel via bike with your dogs?
