Our current dog is getting old and we want to get another when she dies, but the problem is we need a medium-large dog(dad hates small dogs) that will not chase chickens. Any ideas? Oh! and must be able to get along with small children as we have a 5 year old and a two year old at our house. The reason I thought of this is because today our neighbor's dog chased our chickens and scared the poop out of me as we have a special needs chicken who cannot run well.
