Okay, so I know this one has to do A LOT with an individual dog's personality... But, statistically speaking, which are the breeds that are less likely to kill small pets? Like ferrets, mice, etc. Just out of curiosity, since I know many people with small pets. I've been reading that herding and companion breeds are less likely to do this, while hunting (duh), molossoid and terrier breeds are the ones most likely to injure small pets. What is your opinion on this?
