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.
#1: poor kitty! :( Hopefully these tips can relieve him of some stress.
Instead of adaptil, which are calming hormones for dogs, you can get Feliway which is for cats. It is a bit pricey but it works really good for many cats
#3: I hope your mom finds these tips helpful! Yes calming treats could also work :) but I think they will just work for a very limited time (1 hour?). With the product I linked you, you plug it in power outlet and it will keep releasing hormones until it's empty. You can buy refill when it's empty if it is still needed
