We are thinking of purchasing a travel trailer. We have been wanting one for a while. Now that we have a dog we thought this way we could bring him to places with us.. I guess we haven't really put much thought in it. Any of you travel with a dog in a travel trailer? If you have to go somewhere can he be left alone in the trailer for a short period of time? What are all potential good pros and cons? We plan to use it for camping, hunting, or even just a vacation....
