All our dogs have long chains for lots of room. They all have dog houses with lots of shavings for warmth. The nylon collars stretch out or come unlatched if one of the dogs pulls the slightest bit like when a deer passes in the woods. We never had a problem with chain collars until this point. My lapse in responsibility did cause this because I didn't specifically tell the kids to check collars when they feed/water. Puppies are cute and lovable. Then children get older and don't care to spend time with them- it happens every day. When I do the dog care I play with them, brush them etc. I can't lay blame on the kids but i do feel that they should have noticed before hubby did since he hardly ever goes around them. Same story, different family: everyone brings home animals but lose interest then they all belong to mom. We were in the process of finding her a new home already. Ashamed doesn't begin to describe how I feel. If I can't do it all then I shouldn't have them. It will make my hubby happy to see my chickens go.
I know how that can happen.....But I agree with some of the other posters that all or none is probably not the answer. You just hit a low spot and need to reevaluate what is going on. Maybe keep one dog and some chickens. In my experience one dog is much less likely to roam when he/she doesn't have a buddy....just like kids

Good Luck!!
