I think socialization may have a lot to do with dogs liking or disliking certain breeds.

Oz, who was by far socialized a whole lot more than Murph or Maddie, hasn't met a dog or breed yet that he doesn't like. He loves everybody.

Maddie, who I didn't really socialize at all, she couldn't care less to make friends with any dog, regardless of their breed. She wouldn't go out picking a fight. But they better stay out of her space and my space or she's going after them.

Murph, who I did socialize somewhat, does seem to have some breeds that he likes and some he doesn't. He absolutely adores Goldens, because he had a Golden buddy as a puppy, named Hobbs, that he got to play with quite often. On the dislike side, I've yet to see him like another terrier. Other terriers seem to get the strongest negative response from him. I don't know if it's body posture, because other terriers seem to have a cockiness to them or what exactly he reads in them that sets him off, but there is a major dislike there. He's also had strong reactions towards Rotties too. He was fine with Labs, until my cousin's Lab picked a fight with him, now they're on the list too.
