Research Update – Domestication has not Dulled the Guinea Pig’s Intelligence
Hello, Frank Indiviglio here. The Guinea Pig has been domesticated for over 5,000 years (please see article below). It’s no secret that domestication can radically change an animal’s appearance – most taxonomists now consider the Domestic Dog to be a subspecies of the Gray Wolf, and not a distinct species – but you’d never guess that when viewing a Maltese and a Wolf side-by-side!
Domestication also affects survival skills – while Cats, Ferrets and some Dogs may slide seamlessly from pampered pet to “wild” creature (I’ve seen photos of a feral Husky leading a Wolf pack and bringing down a Caribou), others, such as Sheep and Chickens, usually cannot. Brain size may be reduced as well, with domestic animals usually having smaller brains than their wild ancestors.
Domestication’s Effects-Brains and Brawn
However, according to a recent (March, 2010) article in the journal Frontiers in Zoology, while domestication has reduced brain size in Guinea Pigs, it apparently has not affected their problem-solving abilities. Researchers at Germany’s University of Munster found that domestic Guinea Pigs were actually better at deciphering symbols than were wild Cavies (their presumed ancestor). The Cavies, however, proved physically stronger in demanding tasks, such as swimming.
The animals used in the test were placed in a tank of water and had to find a platform hidden beneath the surface by using symbols on the tank’s walls as a guide. I thought this to be rather complicated for an animal that does not normally spend much time in the water, but all were able to complete the task (not sure how good I’d do!).
The researches theorize that long association with people and the mazes and cages they create has led the rodents to evolve their unique problem-solving abilities.
I’m sure that some of you have your own “smart Guinea Pig stories” – please write in!
Thanks, until next time,
Frank Indiviglio

Well, I just bought my 2 guinea pigs in december, so I haven’t really had a chance to test their intelligence yet. They did do a great job at taming, though, I was actually impressed. I wouldn’t make them swim, though, can anyone think of other methods? I’ve noticed they do learn fast, and for instance when i say “salad” one of them starts wheeking. When I say “up,up” the other one jumps in my hands so that I let her out for playtime.Otherwise she isn’t sure if she should jump
Good article!

Hello Roxana, Frank Indiviglio here.
Thanks for your interesting comment and the kind words, much appreciated.
I agree – swimming is a bit much! However, the method you’re using, associating a reward with an action, is perfect…especially impressive that one jumps into your hand, as that is more than a simple food-association. Continue with some other basic associations – the more they learn, the quicker they will be to acquire new skills. Eventually you can introduce more complicated actions – i.e. pushing a ball in order to get a reward. You might use an especially favored treat (carrots work well) when training them.
Good luck and please keep me posted…its very useful for other guinea pig owners to read about your success.
Best regards, Frank Indiviglio.
