Hair Rings in Chinchillas

Rings of Hair on the Penis of Chinchillas

If your male chinchilla is experiencing difficulty mating, it may be on account of hair rings. Hair rings are a condition that develops in male chinchillas following sexual intercourse in which a ring of hair may surround the penis within the foreskin and cause serious complications, including inability to mate with the female. Male chinchillas, especially those used for breeding, should be routinely checked for the presence of hair rings to prevent other complications from developing.

You should check for hair rings if your male chinchilla grooms itself more than necessary, has difficulty urinating and/or licks its penis excessively. The veterinarian will treat male chinchillas with hair rings by giving them a mild sedative while removing the hair ring. He or she may even teach you the proper technique for removing hair rings so that you can do it at home.

It is important to provide your chinchilla a quiet area to rest and recover after the treatment for hair rings. In addition, keep the recovering male chinchilla separate from a female chinchilla to prevent any attempt at breeding till full recovery.
