Hi. Had I given this a thought before? Of course. It would be presumptuous to say either way; however, I will attempt to share my observations in a factual, yet "gay" way. My dogs do talk. They talk to me and each other. They have told me that they don't go sniffing buts to find out what they had last night for dinner, but to find other facts about each other. If you notice 2 dogs "squaring off" at one another, they do swing forward. One of the most vulnerable areas for a dog is it's hind quarters. To show dominance, a male dog will mount another male dog. This shows he is stronger and the other will succumb. This is not a sexual act, but rather an alpha dog. To the best of my knowledge, the only animals/fish that have gay tendencies and procreate for fun are humans, dolphins, and possibly whales. (not sure about the whales.) All other animals do it for survival of the species. Pleasant or not, the species will survive. That's the motto they live by. I hope this helps and have a great day.
