We have a 1 1/2 lab mix that we rescued. She is afraid of loud noises mainly from trucks, we live right next to an expressway, so lots of trucks around. In the last 3-4 days she will not walk outside. We have to carry her to the door she will walk out once the leash is on but start shaking and try to run back inside. She will only stay out if she needs to eliminate but then try's to run right inside. Up to this point she LOVED going for walks but now it seams like she's just wants to stay indoors. She'll run around the apartment and play with us inside just very scared, distracted & overwhelmed outside.
