Can I actually use a trailer designed for kids to haul my dogs around? Ive been looking for one to carry my puppies around but they are too expensive brand new so I found one one craigslist, but it's a kids trailer. Is there any law about this or something? The trailers are rated to carry 100 lbs and my puppies are 50 and 30 lbs. Thanks for any input.

Here's the trailer I am interested in: http://sandiego.craigslist.org/bik/195536837.html
