CoCo, our foster rescue dog, needed some help in overcoming her anxiety about riding in the car. This video is how we approached making her a less stressed traveler.
Socializing older dogs can be somewhat of a challenge. It very much depends on previous experiences. For instance, the new to rescue dogs family may not be aware of how subtle some dog body language actually is. On the other hand, experienced doggie people could think the dog is saying one thing, but really means another. So just remember when you feel yourself overwhelmed, their behaviors are learned. It will take time to relearn new associations.
