Dog-friendly mouse hunting strategies after a year of using standard products?
There is a "home brew" and a commercial form of "bucket-trap" which basically lures them out to a freely rotating element baited with peanut butter and drops them into water to drown. If you build it with a hole in the side and use a lid (as the commercial version I recall is built) it's fairly dog-safe as there's just the hole in the side (typically with a ramp) for the mice to crawl in. The illustrated version would be not dog-safe at all, as it's open and appears to be using antifreeze (suggested when using them in the winter in unheated buildings.)



There are also the enclosed repeating traps which are dog-safe, since again, the mice have to crawl into them.



How well either works depends on your mice.
