It is now new years eve and there will be a lot of fireworks making scary and loud noises which terrifies a lot of dogs.

Desensitizing your dog gradually and slowly is always a good thing to try but you have to do this several months ahead of time.

As suggested in the other thread buying adaptil or any other calming hormones/dog treats might relieve a bit of the stress, as well to keep them somewhere isolated from all the loud noises. As someone suggested the noise could perhaps also be dampened by playing loud music.

Unless your dog is so terrified that you have to drug them I think a calming activity(ies) might also serve as great help

Anything that keep your dogs nose occupied is really distracting and calming. Maybe nosework? You could also take some of your dogs kibble (or treat) and spread it around, hiding it in the room for your dog to find. Or hide their favourite toy if they prefer

Giving a bone or a kong is also an idea. Lickimats also helps to create calmness as it is calming for many dogs to lick stuff.

A kong is a trademark with toys known to be really sturdy. Their most famous one, mostly just refered as "a kong" is the one you can see on the picture above. You fill them with food so that the dog gets occupied figuring out how to get to the food. To make it last longer you can freeze the food in the fridge and serve it frozen solid

If you need a list on what food is safe for dogs to stuff your kong with, you can find it here

A Lickimat is the object you see on the picture above. You can smudge any filling or paste-like edible for the dog to be occupied licking. The paste-like edible can be also be frozen to last longer. Crushed edibles as powders works just as well.
