I think what the dog on the left could have wanted to say to the "dog" on the right was:
- You are not a bloody dog at all though, are you? You are just using my identity to get off, you dirty bastard. This is biological appropriation. We dogs have been rescuing dying solders and mountaineers for you for ages among other awesome stuff we have been doing all over the world sacrificing our lives for you and you reduce us to this shit so that you can cum? What a fucking liberty. And you are also awful at this man, that snout and those ears....oh man, this is offensive. You also smell like shit. And don't get me started on those socks, you look like a bitch and not in a good way. I am so hurt, what do you have to say for yourself?
The "dog" on the right:
- Well, it's a dog's life I guess.
The man in pink shorts:
- Buster! Come on. Come on, boy. Let's go. No, no not you, man.
