Agree with Tony on both his replies. That is totally not acceptable for someone to enter your premises, rented or not, without notification. I would be talking to the manager in a heartbeat!!!
Hi. Are you saying he comes into your home without permission or supervision? That is illegal in most countries (except in an emergency where life is threatened). I would report it to the authorities. Tony
Well we live in an apartment and the maintenance man keeps coming in when we are not home and I have asked that he not do that and well she started acting funny when he started coming in and I was worried that he was doing something!
Hi. Sniffing is a very natural thing ... for one dog to do to another. Some dogs are okay with this, even when a human does it, but not all. Sniffing can be interpreted as a dominance activity as well as a communication skill. For example, the dominant dog will often sniff another dog, who may be submissive, but if the submissive dog sniffs the dominant dog, it can cause an issue. I think you may have confused your dog, assuming she is submissive towards you.
Considering the response of your dog, I wouldn't repeat the activity. For one thing, if your dog were to snap out of fear or aggression, your face would be far too close and this could have serious consequences. I would just stick to the normal interaction between human and dog, i.e. stroke, pat and cuddle.
