Answer
Rabbits and guinea pigs cannot successfully breed. There would be no offspring. They are not closely related. In fact, rabbits are not even rodents.

As for loosing the hair, as long as there are not actual bald spots, he is probably just shedding. This is a natural thing where the old fur comes out to be replaced with new fur.
