Or having health issues. Rescue have said no to you for a reason.
Discounting a breed, especially a CKC, for health issues isn't being picky. It's being responsible.
I didn't want yappy either, OP. That's why I went large! I have yet to find a small dog that isn't known for its vocalness, although I accept there are exceptions to the rule in these breeds!
I wanted a GR without excessive shedding so I went for a retriever/poodle. Mine is crossed with a standard and there are no guarantees on size anyway as obviously they're a cross, but if you do your research you can gauge size a little from previous litters.
If mine was supposed to be super intelligent, she didn't get the memo! She reacts to her environment, so if my boys are being boisterous, she joins in, but whilst they're at school or having downtime, she's really chilled.
Australian Labradoodle, as mentioned already I think, is also a good shout.
