Absolutely.
My dog isn't really that interested in other dogs but if we meet another dog of the same breed she's always happy to greet them and she'll look up at me as if to say, 'look at this dog mum'.
She also more comfortable saying hello to dogs of a similar small size to her.
It's the same when they see their friends.
Some years ago we met a very young papillon puppy in the park (my dog's not a papillon). It was the puppy's first time out. They played together and really liked each other.
We'd meet in the park from time to time and they became firm friends.
I don't know what happened but we didn't see them for months, then one day we saw a papillon over the other side of the park.
My dog got very excited running over to meet the other dog only to realise, when she got close, that it was a different dog.
Her disappointment was obvious and so sad to see.
Her tail dropped and she just turned and walked away. I felt so sorry for her.
