We are looking to get some chicks in the spring. We also have a large iguana, cats and 2 small boys. My husband would like to get a dog. He does not like us being so far out in the country without a little bit of protection. While I know all dogs are individuals, and all puppies need a lot of working with.... what breeds of dogs can you think of that won't bother the smaller animals, be good with the kids, and keep an eye out for strangers? Thanks!
