I have a Cocker Spaniel...she is my "velcro dog"...
Her temperment is very friendly and gentle with family and close friends (people she sees often) She is a little nervous around strangers. She usually sticks to me untill they've vistited for awhile and she feels better.
When she was younger (she's 4) she had a "nervous pee" problem...she has mostly outgrown that, but, I mention it because we had another Cocker and he did the same thing.
She loves to fetch, gets along well with our adopted sheltie, never bites.
She's hard headed and doesn't always come when I call, and loves to chase birds and squirrels. She loves to get dirty...
The other Cocker I mentioned before was a total opposite. He was domineering, and a biter. Obedience training and neutering did nothing to make things better. He eventually bit my DD in the face, in an unprovoked attack and we had him put to sleep. The vet assured us, some dogs whether due to breeding or heredity are just mean. We got him at a pet store, and our girl came from a breeder.
I've pointed out the good and the bad, I'm not sure I could have another. But I love the one I have!

Anything in particular you want to know?
