It is not only dogs, but also cats, rabbits, small birds and other animals that can be frightened, or even go into a life-threatening state of shock, when the rockets go off on New Year's Eve.

- It can get so bad that they even die from fear and from the stress that arises.

If the animal has an underlying heart disease, it can be extra dangerous, says animal nurse Anna Forsblom at Awake animal hospital.

Shock can be treated in many different ways because it is a very broad condition.

But fundamentally, it's about getting organs that are at risk of damage to function again.

Should never be left alone

Animals can also hurt themselves when they run away to hide from the rocket sounds.

If they are outdoors, they can also tear themselves from the leash and then there is a risk that they will injure themselves in the forest or traffic.

Anna Forsblom emphasizes that it is important to never leave an animal that is frightened by noise alone.

- As in any situation, you don't leave someone, such as a child, alone in a scary situation.

In the worst case, it has happened that people who come home on New Year's Eve find their lonely animals dead.

Surprised at the ignorance

According to the zookeeper, Awake Animal Hospital cares for between five and 15 animals on New Year's Eve.

With his 25 years as an animal keeper, Forsblom is surprised by the lack of knowledge that still exists among many animal owners when it comes to protecting their animals on New Year's Eve.

- I am surprised every year.

There are lists of what to do, but still they are happy to call us, on New Year's Eve, and ask for reassurance.

But by then it is probably already too late and their animal is very stressed.

Actions should be started well in advance of the New Year.
