Can Guinea Pigs Go Outside in The Rain? Let’s Find Out

We keep the guinea pigs in a cage in domestic conditions, and we offer them all the benefits they can have, such as optimal temperature, timely nutrition, a peaceful environment, etc.

Can guinea pigs go outside in the rain?

Guinea pigs should not be outside in the rain, because they can get pneumonia, hypothermia, anaphylactic shock, and other health problems.

Guinea pigs in the wild are often exposed to rain and become wet, causing disease. However, guinea pigs in the wild usually have shelter in their burrows to avoid the rain.

In today’s article, you will find out what happens if you expose your guinea pig to rain, what the dangers are to their health, and similar questions related to the topic.

Can guinea pigs go outside in the rain?

Guinea pigs should not be exposed to rain as they will get wet and may get sick. When guinea pigs are exposed to rain they can get:

  • pneumonia
  • hypothermia
  • anaphylactic shock
  • bacterial and fungal infections
  • bad smell of fur

All of these diseases and health problems from exposure to rain can reduce the lifespan of a guinea pig.

So let’s take a closer look at all these problems and diseases that can make a guinea pig sick when it is exposed to rain.

Guinea pigs can get pneumonia from rain

If a guinea pig is exposed to heavy rain, it is very likely that it will get pneumonia.

Guinea pigs get pneumonia from the bacteria streptococcus pneumonia, but we must emphasize that the presence of the bacteria does not automatically lead to the occurrence of pneumonia.

When guinea pigs are exposed to rain, they get nervous and get stressed, which weakens their immunity and then the bacteria streptococcus pneumonia defeats your pet’s body and pneumonia appears.

Symptoms of pneumonia in guinea pigs are as follows:

  • high temperature
  • lethargy
  • the rough appearance of fur
  • breathing problems
  • inflamed joints
  • loss of appetite
  • weight reduction

Pneumonia in guinea pigs can be treated with antibiotics, but treatment should be started as soon as possible.

Pneumonia can weaken immunity and then your pet will not want to eat, which will further facilitate the work of bacteria throughout their body.

If pneumonia continues to spread and the guinea pig is not treated with antibiotics, then fatal consequences and death can occur.can guinea pigs go outside in the rain

Rain causes hypothermia in guinea pigs

When guinea pigs are exposed to rain they can become hypothermic.

Hypothermia occurs if guinea pigs are exposed to low temperatures for a long time.

Guinea pigs are not used to cold temperatures because they come from the Andes in South America and are used to warmer temperatures.

For guinea pigs, any temperature below 60 F is considered cold and can harm their health.

Hypothermia can be very dangerous and cause the death of guinea pigs, so it is very important to dry your pet immediately.

When guinea pigs are exposed to rain, their fur gets soaked and dries much more slowly.

The more a guinea pig is soaked, the more it has to use its body heat, which wears out the organs and causes them to weaken.

Guinea pigs cannot withstand hypothermia for more than 24 hours, otherwise, they face the following problems:

  • hypoglycemia
  • problems with the respiratory organs
  • hearing problems

The longer they are exposed to hypothermia, the more alarming the consequences will be for the guinea pigs.

The fur will start to have an unpleasant smell

When the fur of the guinea pigs gets wet from the rain it will start to smell very unpleasant. This happens because their fur contains natural oils that help keep them warm and wick away moisture.

The bad smell of guinea pigs appears due to rain, dirt from the environment where the guinea pig moves, and the oils in the fur itself.

When guinea pigs have an unpleasant smell it affects other guinea pigs who will start to avoid the wet guinea pig and may start to reject it from the environment.

They may even start attacking him because they won’t want their friend around them because of the bad smell.

Guinea pigs go into anaphylactic shock from the rain

When the guinea pig gets wet in the rain, it will cause anaphylactic shock and it will have the following reactions:

  • decrease in heart rate
  • breathing problems
  • body shaking

If the guinea pig is not removed immediately, within a very short time of a few minutes after the shock, fatal consequences and death can occur.

When guinea pigs have anaphylactic shock, the lungs and nerves in the spine begin to have problems and all other organs in the body fail and the guinea pig dies.

Rain can cause bacterial infections in guinea pigs

When guinea pigs are exposed to rain they can get bacterial infections more easily.

The longer guinea pigs stay wet, the more they are at risk of developing bacterial infections from dirt and moisture.

When bacteria build up on the fur of the guinea pigs, they can then be transferred to the eyes, nose, mouth, and other parts of their body.

On the other hand, when the guinea pig has dry fur, the chances of bacterial infections are much lower.

Does the guinea pig get scared if it rains?

How to safely leave guinea pigs outside in the rain?

If you decide to keep your guinea pig outside for a while, they need adequate protection if it rains.

For this purpose, you will need to make a suitable shelter for him such as a house or a hut that he can enter whenever it rains.

But you have to take care that the temperature outside is not too cold or too hot for them, although the cold weather is more dangerous because they are not used to cold temperatures because they come from warmer places.

Does the age of the guinea pigs affect when you expose them to the rain?

If young and older guinea pigs are out in the rain they have a greater chance of getting sick and developing respiratory problems.

The most resistant are the guinea pigs that are in the best health position, that is, the adult guinea pigs that then have the best immunity.

Regardless of age, if the guinea pigs get soaked in the rain, you should dry them as soon as possible so they do not catch a cold.

Does fur protect guinea pigs from rain?

The fur of guinea pigs protects them from rain, but only if the rain is not intense. Their fur helps the water slide down without soaking the guinea pig, thus protecting them from soaking.

The fur of guinea pigs consists of three layers that protect your pet from rain:

  • cuticle
  • cortex
  • medulla

Such a composition of the fur especially helps them cope with the cold better in the winter, but during intense rain, they will still get wet and may get sick.

What to do if the guinea pig gets wet in the rain?

If the guinea pigs get wet from the rain, you need to react immediately and dry them so they don’t get sick.

Take a dry towel and immediately wipe your pet, which will save him from health problems. You can also use a hair dryer, but be sure to turn it on to the lowest setting when drying your guinea pig.

The sooner you dry it, the better for the guinea pig and you will certainly save it from developing pneumonia or other problems.
