How to deal with people who poison dogs in the community?

First of all, you have to find out why someone wants to poison the dog. I don't think anyone would want to hurt a dog for no reason. Sometimes some dogs are really annoying, such as defecating everywhere. Try not to let this happen. Secondly, there should be cameras in the community. If there is such a hateful person, it can be solved through legal channels. If someone secretly poisons the dog, it's just squatting. What you said about rat poison should be misunderstood. Maybe they really just ... I want to kill rats, but that doesn't mean you can communicate with people in the community. It's best not to let the dog eat unclean things when walking the dog. If dogs run around the community unattended, it will affect others.
