Chows and cockers. Only two breeds I was really leery of when I worked at the vets. Untrustworthy.
I don’t feel comfortable characterizing a breed as ‘untrustworthy’, but they are certainly unpredictable!
I have met a couple very nice, gentle chows, and one very aggressive one (who lives down the street and chases my car) but they have all been stand-offish. I guess it’s the nature of the breed. It almost seems unfair to give them that aloof nature, side by side with that fluffy, ruffly neck and adorable teddy bear face! One’s first instinct is always to wrap your arms around them and bury your face in their mane, when all they want is to be left alone.
Cocker’s are a whole ‘nother ball game. Bitey little monsters.
