A problem associated with with boredom in which a guinea pig chews its own hair.

External parasite that lays its eggs on the shafts of hair, often around the face, ears and shoulders and causes intense itching.

An infected swelling within a body tissue, containing an accumulation of pus.

Contrary to its name, this infection is not due to a parasitic worm, but rather a species of fungus and causes an itchy rash, hair loss and crusty scabs.

Caused by the misalignment of the incisors causing the overgrowth of teeth.

Occurs in animals housed on wire-bottom cages or urine soaked bedding causing ulcers on the feet.

Symptoms include loss of appetite, blood in urine, straining to urinate and a hunch posture.

One of the most significant diseases of pet guinea pigs and can be caused by several bacteria. These bacteria tend to be 'opportunistic,' meaning they infect susceptible animals, multiply, and cause disease if the opportunity arises. Infected guinea pigs may be off food, have discharge from the eyes or nose, sneeze, or have trouble breathing.

Can be caused when the normal bacterial flora of the gut becomes altered or unbalanced (sudden food change), parasites or bacterial infections.
