Now, Sir Hamish, this is another area of relevence to me, my dog I had before the 16 year old, Harry was his name, it turns out he was gay, suppose being a c.ocker spaniel he was doomed from the start, the aul' pair got a few bitchs over but instead of getting laid, he was more interested in licking his balls, and look to mount some doggie fellas, so yeah, its entirely possible to have a gay dog!!! (Honestly thats a serious post!)
