Side-effects of Giving Chocolate to Guinea Pigs

Chocolates are harmful to your pet and should not be given at all. Some of the health risks associated with chocolates are-

Increased heart pressure

As mentioned above, the chemical theobromine found in both chocolates and caffeine is harmful to your guinea pig’s heart. This chemical speeds up the heart rate of the animal by stimulating the nervous system and increasing the metabolism rate. Such situations are harmful to an animal with a small body such as a guinea pig. The increased heart rate can be too much for your guinea pig to handle, and can even lead to death in some cases.

Rapid weight gain

Chocolate is very rich food, loaded with carbs, sugars, fats, etc. These nutrients cause maximum weight gain in humans as well as animals too. The same is the case with guinea pigs as well. Guinea pigs are known to be hoggers already, and giving them chocolates won’t make them stop at just one bite.

Urinary problems

Apart from the harmful chemical in chocolates, there are other two nutrients in chocolates that are extremely harmful to guinea pigs. Calcium and phosphorus together can harm your guinea pig’s urinary system very badly. Excess presence of these nutrients can cause blood in urine, kidney and bladder stones, painful urinations along other urinary tract infections. If these issues are not cured on time, they can lead to more serious problems such as renal failure.

Digestive issues

The presence of high sugars and theobromine in chocolates can instantly make your guinea pig feel sick. These contents will cause abdominal pain and severe cramps in guinea pigs. The sugar content can cause digestive complications in your pet while theobromine can make her feel nauseous.

What should I do if my guinea pig eating chocolates?

If you have left your chocolate open on the table only to find your guinea pig enjoy every bite of it, don’t panic!! Check the amount of chocolate your pet has consumed. If it’s only a small amount, then your pet should be fine. But, there are chances of some minor digestion problems, along with cramps. However, in case a big amount is ingested, there could be severe diarrhea along with digestive complications and nausea.

Keep your guinea pig under thorough observation and look out for these symptoms. Your pet must remain hydrated, so make sure to give her water and maybe some greens to chew on. Monitor for any serious signs, analyze the stool, observe if your pet looks sickly. If symptoms persist for long, then it is best to take your pet to the vet.


Chocolates are very healthy foods for humans, especially dark chocolates, but not so for guinea pigs. While guinea pigs will love the taste of chocolates, they are harmful and can lead to serious complications when ingested. From diarrhea to urinary tract infections, chocolates can mess up your guinea pig’s health system.

It is best to look for other alternatives as treats for your pet. There are delicious fruits that are safe and taste sweet, such as peaches, which your guinea pig will love. If at all, you are very keen on letting your pet try chocolate, you can give a tiny amount once in a blue moon.
