Yes. I doubt that if the man asked her nicely to put the dog on the leash, her response would be to call the cops. My guess, that even if he asked nicely the first time (although I am not sure that he did - having dog treats on him implies that he wanted to get confrontational) and she reply in the form of "get lost", he than said something to the effect "if you will not put the dog on the leash, I will do something that you do not like". Now, this is a threat. After that he starts calling the dog offering him treats. This can be viewer as an attempt to poison the dog. At that time the girl got scared that the guy wanted to poison her dog, and, probably, attack her after. Now, a scared person tries to defend herself. She did not have a gun, so she used the only weapon she had: call the police and play the race card to make sure the police will come sooner (and, hence, the guy will not have time to do all the bad things that she thought he will do based on his original threat). Yes, she may not have behaved most rationally, but she was under a lot of stress. And, strictly speaking, everything that she told the police on the phone is true. Note also, that it was the guy who planned this confrontation (otherwise, why he took the got treats with him). She was simply walking with her dog. Yes, the dog was supposed top be on the leash, however, her behaviour cannot be perceived as violent. Offering food to a dog while having heated confrontation with the owner can be seen as violent (trying to poison the dog), and it was premeditated. I'd say, it was the guy who was mostly at fault.
