[MENTION=2102]SillySapienne[/MENTION] has three dogs, and I swear their MBTI types are all very noticeable.
For the most part, I think animals tend to be Ss and Fs.
Jack - Miniature Dachsund - ISFP
Blanca - Pitbull - ESFJ
Frankie - French Bulldog - ESTP
These are all really just based off their dominant functions.
Jack is the most independent dog I've ever seen; it's ridiculous; if you take him on a walk, and he wants to go one way, if you try to go the other way, he digs his feet into the ground and will not budge. No matter how much you try and cajole him, he will not go the direction you want him to. It's his way, or the highway. If you won't go his way, then he'll just start walking back home. It's fucking ridiculous. Because of him, I understand why Fe users call Fi users selfish. He's totally an Fi-dom.
Blanca is the sweetest fucking dog I have ever seen. She's a big ol white pitbull, and I love her to death. Her big smiley face is the screensaver on my phone. I have never met a dog so needy, though. She literally needs someone with her every second of the day. All she wants is to give and receive love, and she would cuddle non-stop, all day long, if you'd actually willing to. She's also super-obedient, and super-submissive. Total Fe-dom.
Franky is the newest addition to the pack, and he's like hell on wheels. The little guy is just a fucking hedonistic pleasure-whore. Food, sex, excitment, food, sex, excitement. I swear the dog would OD on drugs if he knew how to. I'll take him to the park and throw the ball around with him until he starts puking up white foam and just collapses. Then, after five minutes, he's back and ready to do it again. Total Se-dom. You can see it in his eyes.
