Although garlic is a super-nutritious diet for humans, it is not suited for guinea pigs.

Garlic can upset these small animals’ stomachs and irritate the digestive tract because of their sensitive digestive systems.

Guinea pigs who consume garlic may experience a variety of health issues, including depression, dehydration, appetite loss, and stomach pain.

In serious cases, consuming too much garlic can potentially cause kidney damage.

One reason garlic should be avoided in guinea pig diets is because it is toxic to them.

Garlic contains thiosulfate, a compound that can damage red blood cells and cause hemolytic anemia in guinea pigs.

Moreover, garlic has a specific spicy flavor that can cause a burning sensation in the guinea pig’s mouth and throat, leading to discomfort and pain.

What Are The Risks Of Feeding Garlic To Guinea Pigs?

01.Digestion Or Stomach Problems

Garlic is very bad for guinea pigs because it can upset their stomach and irritate the gastrointestinal tract.

Diarrhea, vomiting, stomach pain, dehydration, appetite loss, and sadness are a few signs of an upset stomach and digestive issues.

Don’t worry if your guinea pigs accidentally consume a small amount of garlic; nothing serious will happen.

Just make sure they have enough water. However, if a guinea pig has consumed a significant amount of garlic, consult a veterinarian right once.

02.Risk Of Anemia

Garlic and other Allium family members, such as onions and leeks, contain thiosulfate, which is toxic to small animals, such as guinea pigs, dogs, and cats.

In guinea pigs, the substance thiosulfate can harm red blood cells, leading to hemolytic anemia.

Rapid breathing, weakness, irregular heartbeats, black urine, and yellowish complexion, are some symptoms of anemia.

According to scientific studies, the amount of garlic and onion that may cause toxicity in animals is equal o 0.5% of the animal’s body weight.

Garlic is riskier for guinea pigs since it is more concentrated than onion.

The guinea pig’s mouth and throat may feel like they are burning after consuming this flavor.

Therefore, it is preferable to avoid giving garlic to guinea pigs to prevent these unpleasant issues.

05.Urinary Problems

One of the risks of garlic is that it has calcium and phosphorus.

These two nutrients work together to create strong bones and bone tissues.

For instance, excess calcium deposits might cause kidney or bladder stones in guinea pigs.

This makes urination painful, with even possible blood in the urine if not cured in time.

If left untreated, the kidneys could stop working.
