Do dogs recognize breeds?

Do dogs have the sensory abilities and mental capacities to tell different breeds apart? Do they act different to members of their own breed? I noticed that one my dogs would always freak out when he saw Bernese Mountain Dogs, and they'd always play with other boxers the same way they played with each other. I'm not sure how much of this is dogs recognizing breeds and how much is me projecting characteristics onto their behaviour.

I've worked with dogs in in shelters and rescues, and I've never seen any behaviour that would indicate that they act differently towards different breeds. Body language is the main way in which dogs communicate, and the size/shape of the tail isn't important compared to the way it's being held, for example.
