Our dogs are crated. We have a sign on the RV, that their are dogs inside and where the crate is in relation to the door. Also shows contact phone numbers for other family members who will guarantee payment for services should they be needed. We also carry cards with us saying we have dogs in the RV and the name, phone number and site number of the campground we are staying at. When planning trips, I spend as much time researching local vets as I do destinations and stop overs. Still travel with fingers crossed.
