This is our puppy (she is actually about 6 yrs old). On new year's our neighbors decided to set off fireworks and she wanted nothing to do with it LOL. When she hears loud noises such as gun shots or fireworks, she gets scared and has to be right next to someone for the next 3-4 hours. On new year's she actually crawled under the blanket (which she never does, she always sleeps at the foot of the bed) and was laying right up next to me. Poor puppy was terrified.
I never used to put much into making sure the dogs were in for the night on the fourth of July or new years until I moved in with her (my husband, Aarron had her before we met). I have never had a dog that reacted badly to loud noises. I completely understand the warnings now to bring your pets indoors on these nights.
Have a great Day!
