We've only ever had rescue dogs. Get them used to your routine at home. I used a digital recorder at home to record any anxiety by them from quick trips to long ones when we couldn't take them. Just like you have to socialize a new dog to the family you have to get them ready to go for rides, camping trips and anything else that comes up. Tipper and Polar have passed but they still travel with us. We take the urns with their photo on the front with us. When we put the RV in the driveway Pasha and Ginger pick some, actually all, of their toys by the door to take with them. We also leave music on when we have to go somewhere when they can't go and found out that they like soothing music (no vocals) on and they stay quiet.
