Dogs do not think in terms of "homosexual/bisexual/heterosexual", but in terms of dominance and submissiveness -- pack behavior. In a pack, the alpha dog and his mate are usually the only ones to breed, leaving the rest of the pack with sexual urges but no outlet. Homosexual behavior has been observed in dogs (and every other mammal). (You may have seen dogs "mounting" other dogs -- this behavior is to demonstrate dominance; it's not sexual.) But dogs have been seen to develop special relationships with other dogs that do include sexual behavior, signs of affection, and stress when their "special" dog friend is absent, sick, or in danger.
