MooMoo doesn't typically door dash but when she see's a squirrel or some other animal smaller than her moving while someone is going out or coming in through the door she rushed out. If she doesn't catch whatever she set her eyes on she realizes that she's outside and makes a run for it. Today I found that when she does catch her prey she will run back inside put it on the floor and make a mess inside. She caught a Texas spiny lizard and would drop it, catch it, then drop it again. We eventually caught it with a tongs and let it outside. Update on leash training: I took her on a kids rolley cart with netting on top so she could have room to move but she gets spooked too easily with the neighbors pulling in their trashcans, people walking up to us, and cars approaching even if we aren't anywhere near her so she just runs. I have a feeling it'll be the same reaction on a leash but she'll probably wiggle out of the leash to run. I'm thinking of getting a cat backpack to carry her easier or maybe get a great dane dog cage to make a mini catio.
