How to Tell a Guinea Pig's Age

At the Los Angeles Guinea Pig Rescue, volunteer Scotty sees many guinea pigs and must determine how old they are. It isn't always so easy if you do not know their history, but there are some ways that you can tell a guinea pigs age. Until a guinea pig is full grown their size is a decent indicator of age, but after that, you must look at other things. The best way is looking at guinea pig's nails. When they are young they are thin small and pointy, and as they get older they get thicker. With repeated nail trims they also lose their sharpness. The bald patch behind their ears is also an indicator. Guinea pigs do not have hair behind their ears usually but it tends to become thinner in that area as they age. Another indicator is the hips. Older guinea pigs have more pronounced hips because of loss of muscle in that area. Arthritis can also be another sign of age. Limited Mobility in the limbs can be a sign of an older pig.
