In this Maine case, the defendant was found liable for trespass after he killed the plaintiff's dog. Defendant asserted that the dog was trespassing on his premises, and was “then, or had been immediately before the shooting, engaged, with two other dogs, in chasing and worrying his domesticated animals, to wit, tame rabbits." As a result, he claimed that the killing was justified. This court first disagreed with defendant's claim that an unlicensed dog is not property because it constitutes a nuisance. This court found that, by the common law, a dog is property, for an injury to which an action will lie.
Moreover, the statute to which defendant claims authority to kill an unlicensed dog only allows a constable to do so after a proscribed lapse.
