If you have her in the crate the little girl will realize she couldn't get out and is safe. I am terrified of big dogs but little dogs don't phase me. Growing up in random military housing dogs over 20lbs were raised to attack small animals and always went after kids. I watched a husky eat my poodle. As well as I can't count how many times I've been chased or attacked by bigger dogs. I keep a small Carry along cage with me that I can put one yorkie in comfortably. It has windows on all sides and they actually feel safe inside. I use it to go to the vet. Bring treats with you and let the little girl give some to your cricket . worst case she dosent want to and leaves your furbutt alone. But cricket will be inside with you and not outside by herself terrified of the fireworks and loud noises. Good luck
