Everyone has squicks. I just don't enjoy anal, giving or receiving. I enjoy proffering handjobs and blowjobs to stud critters, and frotting, but ... popular as they are, just not great about the most popular receiving hole on males.
I've had a few dogs initiate kissing (frenching, to be precise). If they have a clean mouth, I'll oblige and join in. I once visited a "mutt derby" at a greyhound park that was intended to raise money for greyhound rescue. A local radio personality brought her VERY friendly male Australian shepherd and while the dog was introducing himself to me he slipped me some tongue.
That was the first time that happened to me to that extent, but it was surprisingly pleasant. Of course, being that it was a very public place, I put on the whole "ACK! Dog germs!" act. I couldn't help but wonder , though, if a certain other part of him was equally tasty, and if he'd be so willing to share that with me.
When I was quite young, my family had a spitz-type mutt. If we made "kissy" sounds anywhere near her, she would snarl and growl exactly like the dogs in the video. She would also discipline unruly kids (human or canine) with what my Dad called a "bitch slap." She would swing her head to the side and tap the offender with the side of an upper fang and a fearsome growl. She never hurt anyone, but we knew to leave her alone after that.
Every dog I've been with loves to kiss haven't had one uninterested in it
A friend of mines girl will literally lick you to death. Been close to losing oxygen because she just doesnt stop.
Dog kissing is incredibly pleasurable. Dogs do love it although probably for different reasons that we do. I do not think kissing has any sexual meaning for a dog, but they do enjoy it for their reasons. From my experience the wider the tongue the better the kissing.
I also enjoy deep kissing and I enhance the experience by heating the dog up and making the tongue literally hot.
