I like all dog breeds, especially mutts.
My first dog was a Chihuahua named Rusty, technically my dads dog. She was a little fireball. Didn't care much for me being around, might have something to do with my pulling on her tail and ears when I was a toddler. I was outside playing and a Doberman decided it was going to have me for lunch. Rusty broke through the screen door, and ripped the dobie a new one. Got an ear, tip of the tail, and chased it down the street, and away from me.
My second was a Havanese, named Chaz. He played dumb to get free treats from my dad, but he could do all kinds of tricks, just not for my dad. He boxed by standing up on his hind legs and swinging his paws. Confused my wolf dog when he would bat his ears. He loved spaghetti, and is the only dog I've ever met that would toss a burger aside to get to the fries underneath. He only turned to the right, and would make circles if he wanted to go left. It was fun to watch him herd...as a dog bred to herd chickens, he would circle birds and make them move closer together, after a while they'd fly away, and he'd get a bit miffed, and huff and stomp his front paw.
My third was a wolf dog, Corynn. He was submissive to the havanese. Would grab mouths full of food, and drop it in the living room, and lay down and watch TV while munching the food. Also had to shower with me every day. His favorite toy was toilet paper.
Then I got Titan/Buddy. Had to give him to a family friend because he was to big for the apartments we were moving to. He is a black lab, and we get to visit him. He likes to travel under people who are standing by going between their legs. Drool box who loves to lick my head, and would wrap himself around my neck when I would sit on a couch. He has opened the door for my wife and I at our friends house. LOVES pancakes!
Finally there is my current dog, Clover. She's a beagle mix. Really smart, and very vocal. If you listen and talk back, she will hold a complete conversation with you. Her saddle has a clover shape to it. Poor thing suffers from allergies. Her favorite game to play is she will hide something and then expect my wife or I to go find it. Then we get to go hide I so she can find it. Back and forth with that game. She also likes to crawl under the blanket, and nip at our hands to make them jump around. I used to chase her with my hand under the blanket when she was a puppy, so that's probably why she does it to us.
I tend to find the dogs with bizarre behaviors, or make them have a bizarre behavior.
The one dog I wanted to get, but she was to big, was named Precious. She was a greyhound, who was beat into submission by her owner. She was rescued and taken to the pound. I volunteered there, and they were going to put her down because she would only crawl when on a leash. She coward to all people. I spent a lot of time working with her, and showing her that people aren't bad. She would play with me, but only with me. A professional trainer came and tried to work with her some more so she could get a home. She responded best when I was there with him too. He said that I saved her. I kept her from being put down by making her trust people again. Last I heard, she had gotten a home, Had a picture on the board of dogs with a new home, with a lovely younger couple, and a 10 year old boy. She looked happy in the picture.
