FAQ: Keeping Guinea-Pigs Happy & Healthy

Can guinea-pigs be resistant to mange treatments?
The confusion between mange and mycosis is a common one. While it is just possible that an animal is resistant to it, If you find a mange treatment hasn't worked, it probably has mycosis. This is due to fungal activity which should be treated with a specific medication. Severe problems would be treated with a fungal antibiotic.

What if a guinea-pig seems interested in food but won't eat?
Perhaps she is also losing wait. She may have dental problems, which your vet should be able to check for and fix. Since only the four incisors are clearly visible, it is difficult for pet-owners to check how the other 16 teeth are. Overgrown premolars are fairly common, forming an archway over the tongue.

What does a large, black greasy patch at the base of the spine mean?
All guinea-pigs have a grease gland in this area. Females secrete only a little, if any, wax, but males will accumulate large quantities of wax in this area unless cleaned at regular monthly intervals with either washing-up liquid or a medicated shampoo. Ask your vet to recommend one of these.
