What is the best small dog breed for not being aggressive or tempermental?

rottweiler

I had a pomeranian.Sweetest dog ever.

Boston Terrier

I'd suggest finding the best mutt to suit your needs at the pound, they have always seemed to be the best there.

Maybe a pug or westie. Not poodles.

shitzu or pug

I would suggest a shih-tzu. They are generally a 'people' breed and most of them seem to have good temprament. They are not aggresive and love to be cuddled. I luv my little guy - he's a very sweet dog.

Shih Tzu very loving and gentle. Good for nothing but unconditional love and companionship.
