One of the few cases where it could be more justifiable to only do with people and not involve animals. With people, there's a few contexts where it makes sense without being genuinely disrespectful. Some people do it because they're close friends and its all just banter, which is fair and I can mostly understand, even if I suck at it. Then there's dirty talk, which is probably one of the most annoying things coming from most people. Most guys should just shut the fuck up and thrust instead of trying to be witty during sex, and leading up to it, I'd rather they speak with their body and not their hormonally scattered brain. I imagine there are men who feel the same way when a woman does it as well.
Funny thing is, animals understand neither, and imagining that you have the same kind of understanding between the two of you that allows for either, is incredibly laughable. About as laughable as having a sub/dom relationship with your dog, which they also can't understand. Really, if you want to be respectful and caring to your companion, you have to work within the scope of their understanding, and not yours. That being said however, the animal also doesn't care what you call it. (Or should I say him/her instead?) I don't halt my tongue to call my dog smelly whenever he's feeling gassy, but I think the real issue will be what the mind does when you do something that normally comes with more mutual baggage when done between humans, that doesn't exist between human and animal. If you keep describing and thinking of your dog as a horny bitch and something for you to take charge on and use, then you're probably heading towards something abusive. As with anything these days, you need to be watchful of what ideas you let into your head. Or maybe I'm overthinking it, and need to take a nap.
