How can I tell the age of my guinea pig?

Answer by  Dennis59 (86)

It is very difficult to know the exact age of a guinea pig after they reach 12 months or older. Even speicalisits find it difficult to give an exact age. The best they can do is give a close estimate.

It can be almost impossible to tell a pig's age after a year or so old when they reach adult weight. If they are very young they might have pointed sharp nails (as they haven't had to be cut yet). Older pigs can also move more slowly or be less noisy (although pigs have varied personalities).

Pigs increase in weight and length til about 15 months. Length for mature males is 30-35cm and females 28-32cm. There really is no other way to tell.

It is quite difficult to tell the age of a full grown guinea pig. You can't check the size of their teeth like you would a horse.
