Beautiful name for your baby! I have a Bella also, Princess Bella Mia
I have brought Bella with me to the fireworks show. She does not mind it at all. She has been raised around hunters and we live in the country with coyotes and foxes so she does hear loud bangs and it doesnt phase her. She would love to go with daddy hunting.
HOWEVER, we have a VERY mellow medium size older mixed dog and it terrifies him to death to hear the loud bangs of fireworks or gunshots. We dont take him anywhere near loud bangs. I suggest until you KNOW she can handle it keep her home. If the noise bothers her at home you will know not to take her next year. If she tolerates it take her next year and if there are any signs of distress be ready to go home.
Good Luck!
