Are guinea pigs afraid of dogs?

For many dogs, it is in their nature to kill a small animal such as guinea pig.

A well trained dog will not hurt a guinea pig, particularly if it is a breed meant for herding rather than hunting, such as a border collie.

It is unwise, however, to leave the two together unsupervised - just in case.

House your guinea pig in a cage with a top and a closed open and closed area so the dog can not get in to the cage and hurt your guinea pig.
