I have read a lot of the posts on here about neighborhood dogs killing flocks / livestock. We have a new neighbor - a couple purchased the 10 acres next to us and plans to build there. They are not here often an this point, maybe once a week. They bring their hunting dog who is very high strung and wanders all over the neighborhood. They do not watch the dog. For instance the husband is working with heavy machinery with ear plugs in his ears listing to something so there is no way he knows what the dog is up to (not sure where the wife goes when she comes- I think she sits in their truck with AC on). My point is they do not watch this dog. We let them know that we have birds and pets (chickens and ducks - a cat and dogs) that might be free ranging. Yesterday there dog went in our coop (door was open) and killed two hens and my daughters pet Rouen duck she also wounded two more ducks. My husband by chance was outside and was able to stop the attack although it took great effort including getting physical with the dog as she would not respond to his voice commands or his presence. It has taken sufficient effort to keep our chickens and ducks healthy and provide proper housing etc and I have become attached to them as "pets". So I am REALLY upset about this. The neighbor was very apologetic and while I appreciate that the fact that he was making NO effort to control his dog upsets me - he also claimed he didn't know that the animals would be free ranging "for certain" (like that matters). MY QUESTION: I have read our towns animal regulations and I think I can make a complaint that might be taken very seriously - however everyone in our neighborhood has dogs that roam to some degree and I am not sure I should make a formal complaint but I am fairly certain they will not be able to contain this dog. She is nuts. She does not listen well and has run into my house in the past and all over my property w/o stopping to acknowledge my kids or my husband and I. She has a shock color on. Should I make a formal complaint with animal control? I am concerned that it will create issues for all the roaming dogs in the neighborhood - none of which has killed anything on our property (yet). Thanks Suz PS Our birds typically free range during the day and are always in at night. We are keeping the chickens in all day for now but the ducks being messy and loving water are still roaming during the day as we have 10 acres and a pond - and the ducks REALLY mess up the fenced in coop area if left in it. (The coop is large with a separate duck and chicken are inside but the outside fenced in area is smallish and not separated). We are replacing my daughters Rouen duck today with and adult female as she is heartbroken over losing "blackie".
