The Neigbor’s Dog & Cat

The neighbor’s dog and cat would come to our lawn and backyard and poop on the ground.  We want to put some no trespassing signs up – because we don’t have a fence around our lawn or backyard.  But shouldn’t people keep their dogs and cats tied up or bring them out for walks – so that they don’t go pooping at the neigbor’s house?  One time – their dog came running up to me – and I got really scared – and daddy said – the next time the dog comes running like that – he was calling the dog catcher.  So far we’ve only seen the dog a few more times in our lawn – but we found some poop every week – in our lawn – so someone’s dogs and cats are still coming around.  Daddy is going to put something into the lawn – so that the dogs and cats doesn’t come anymore.  But the trespassing signs are going to be up – so that they neighbors are warned.
