My 1.5 year old Jack Russell / Lab mix loves to go outside during the day but not at night. I take her for her last walk at 10pm right before I go to sleep. We live on a busy road and I walk her in the grass swail. A few months ago while she was going potty a car drove by and made a loud noise that scared both of us. Now she runs and hides and won't want to go out. My husband and I usually corner her but he is out of town for the next few days and even though I eventually caught her she did / does growl and snap at me / us. She is not aggressive just scared. Any ideas on what to do? She won't eat treats before we go out but I give her a couple when we come in then I put her in her bedroom for the night.
