Why Your Guinea Pig Needs Vitamin C But Your Dog Doesn't

We all need to eat a complete and balanced diet. We feed our dogs and cats food developed by companies that study their nutritional needs, but if you study the list of ingredients, Vitamin C is not listed. When we prepare our own meals, we have to make sure we consume a source of Vitamin C such as orange juice. Ever wonder why most pets don't need this vitamin?

The vast majority of animals in the world make their own Vitamin C and don't need to consume any. Vitamin C is also known as ascorbic acid. This vitamin is important for several enzyme reactions in the body. It is a factor in pathways making collagen and other substances that are important in healing and preventing bleeding from capillaries. It is an antioxidant and is also required to make adrenaline and dopamine.

Some species of animals have lost the ability to make Vitamin C however. A genetic defect occurred in guinea pigs, fruit bats, capybaras, some reptiles, and many primates, including humans. This defect causes the inability to make the enzyme L-gulonolactone oxidase in the liver. This enzyme allows the body to convert glucose to ascorbic acid, or Vitamin C.

These animals must consume Vitamin C in order to be healthy. That why it is important that people, and these other animals drink orange juice or eat other foods high in Vitamin C.

As far as pets are concerned, dogs and cats make their own Vitamin C and do not need to consume any. It is important, though, to feed guinea pigs a diet high in ascorbic acid. That is why you should feed them a pelleted diet made for guinea pigs and not one made for rabbits. The guinea pig diet contains Vitamin C while the rabbit food does not.

If you have any questions regarding nutrition for your pet, you can ask your veterinarian for help.

THE WORD OF MOUTH

What our patient say

  • "My dog Buster was in pain and wasn’t acting like himself. I scheduled an appointment with Dr. Gill ASAP. He did a remarkable job during the initial exam to diagnose the problem and recommend additional treatments/services to relieve the pain Buster was in. After doing X-rays and blood work it was determined my little guy was suffering from intervertebral disc disease."
    Jotika
  • "This place was awesome. They took such good care of my giant Rottweiler during an emergency. They even called the next day to check up on her. The price was reasonable too. Went back again and the treatment was great yet again. Love that they stay open late and open everyday. So convenient. Thanks guys for treating my girl as is she was family!"
    Mea
  • "I’m planning to travel with my baby cat. In order to do that she has to do a Rabies Neutralization Antibody Testing from certified lab. I was lucky to reach out Dr. Gill. He explained to me throughly and helped me to get it done. I would recommend Dr. Gill to everyone who needs professional and friendly help on their loved pets."
    Hsinti
  • "I’m very happy with the service and prices of the Silicon Valley Pet Clinic. I have gotten quotes from other vets around and SVPC offers the best value! I took my dog in to get some growths removed and get this teeth cleaned."
    Katie
  • "My 16 yr old cat Pete had some green discharge coming from his eye. I recently brought a feral kitten in to care for that my cousin found. I figured that Pete probably got scratched in the eye from the little guy."
    Jeanna
  • "I was very nervous to have her spayed, especially after going through an episode of Giardia. She has been dealing with poop that is not consistent and we are doing some probiotic treatment."
