We have always tried to take Kallie (maltese) with us but we have not taken a trip since we adopted our Yorkie, Toby.  But we plan on taking them with because of the type of vacations we take........sightseeing, antique shopping, hiking, camping.  So it will be very interesting to see how our next trip goes.  BUT as a back-up to taking them with us, if we need to take a vacation where they just can't go, we have a son that they absolutely adore and he adores them so he picks up his things and comes and stays at our house. He eats all he wants, swims in the pool, and just has sort of a mini vacation himself and the dogs have human company and stay in familiar surroundings.  Everybody is happy!
