Do Shelties do well on vacations/camping, or do I need to board my pet?

Yes!  We camp with the Sympa Shelties several times a year.  The dogs are good in a trailer or a tent.  In fact, ours have their very own "doggy tent" (it is really a large screen tent) when we go camping with them.  Camping is a great way to socialize Shelties to different environments, people, and sounds  :)
