If you get a fairly young dog that is not a herding breed (Queensland heeler, collie) it will learn fairly quickly that you don't want it chasing the livestock. When my dog was just a pup, I took her out to the farm I worked and boarded my horse at and she thought she would do what the heelr did--nip at the horses' heels. My horse cocked an ear back, turned her head just slightly and gave her a little kick with her hoof, not hard but enough to say "stop!" I think that was more effective than any training I could give her. She has never done it since. Also, Blaze (the dog) has been around cattle, horses & poultry since she was a few months old so she doesn't see them as something to play with. When I was brooding chicks in my mother's kitchen, her dog was FAR more interested in the chicks than Blaze. But he's a city dog.
Like Rosalind said, dogs are excellent for keeping vermin at bay. We have no coyotes come on our property and rarely see skunks, raccoons or opossums. My dad fights with squirrels in his house an "borrows" Blaze for a weekend or two occasionally. Rodents, cats and wild turkeys are the only animals she's allowed to chase. (The neighbor cats try to fish in our pond)
If you get a hold of a breed rescue (I would suggest a retriever since you have small children at home and they are more tolerant of getting poked and prodded and having eyelids pulled than other breeds) and they can help find an individual to suit your needs. A lot of breed rescues have dogs in the 18 month range when they grow out of the cute puppy stage and haven't settled down yet. Being a novice to the dog world, find a good obedience trainer to work with. Most encourage the whole family to participate.
I never did obedience w/ Blaze (mainly because she ran around on 200 acres all day while I rode fence or moved cattle and I could easily run her down on horseback and was so tired when we got home at night that she didn't run off) When I lived in the city last year, I noticed that my mother's dog had much better "walking" manners. He heeled, didn't snarl at small dogs and didn't wander all over the sidewalk like Blaze does.
Also, because you have small children, figure out a "Keep-safe" spot for the dog where the kids are not allowed to bother it, even for petting. This could be your room, a crate or an out of the way corner. That way when the dog has enough of having its teeth counted by a 3 yr old, it can retreat for a few moments of peace & quiet
