(47,209 posts)and then explain touching or feeding the dog and visiting your yard is totally off limits, as is engaging the child when we are not there to supervise. Abusers will seek out individuals or families who have poor boundaries and break them down further. The whole family does need to set him straight themselves. The only alternative is to wait to catch him in the "act" of god knows what, and even then little can be done without firm evidence.
Police will not take you seriously if you have not at least confronted this person about what can be characterized as harassing behavior.
I would speak with him directly, and possibly involve the police only if I had concerns after the talk. I would bring the dog inside if I could not keep a pretty constant eye on things. He could get sick from eating god knows what.
