Why is my guinea pig shedding so much and drinking more water?

Updated On September 23rd, 2025

Pet's info: Exotic | Unknown - Exotic | Male | unneutered | 1.5 lbs

My guinea pig of a few months started shedding excessively lately and it's getting worse. We rolled a lint rolled over him and a bunch of hair came out.he doesn't have bald spots but I don't think this amount is normal. He's also been drinking a lot more than he was lately. What do?

While there are many possible reasons for hair loss, the most common reason by far is microscopic mange mites. This can be easily treated with medication from your vet. Fungal infections are a close runner-up. Check over this list for the possible causes of hair loss: 1. NATURAL Hair Loss - basically normal shedding. 2. Barbering - chewing the hair either by him or another pig (if you have another one) 3. Parasites: like mange mites 4. Fungal infection 5. Vitamin C deficiency 6. Bacterial infection 7. Low protein diet 8. Age related - like going from a baby to an adult (shedding the baby hair) So, if there is no itching or scratching and no bald spots I would say start with making sure his diet is appropriate and that he is getting a Vitamin C supplement (very important). I recommend Oxbow brand diets and hay. http://www.oxbowanimalhealth.com/products/type/detail?object=1582 http://www.oxbowanimalhealth.com/products/type/detail?object=1530 http://www.oxbowanimalhealth.com/products/type/detail?object=10829 Keep monitoring him and if you notice any itching or bald spots get him to the vet for an exam. I hope this helps. Best wishes!
