Sabrina is left-handed

I was outsiding chasing down some squirrels.(Dad sarcastically calls them "my friends"). It was like 10 degrees and I wanted to come in. Mom opened the door a little bit. She wants me to learn to help myself from time to time. I hate these teaching moments. I try to push it open with my left paw. My left paw goes across my body and hits the wooden door frame. Ok, try again-same result. The third time will be the charm-nope. Neither is the 6th. Ok, now my paw hurts in addition to being cold. I look up at them. Will someone please open the stupid door more or tell me what the secret is. (Stupid dog)
