So here's the situation:
First of all this is all happening in Ontario
My friend's dog was attacked recently by a 6 month old boxer, which despite its age, was strong. She (the attacked dog's owner) was mildly injured as well. The boxer's owner then gave her false info most likely to avoid paying vet bills. The boxer's owner then entered a home in the area.
The vet bill totaled to over $1000 (CAD). My friend was forced to pay out of her own pocket as she had been given false contact information. She also had to be vaccinated as no one knew whether or not the boxer had its rabies vaccine or not.
She called the police, and reported the house mentioned earlier. The police questioned the homeowner, and they allegedly told them they barely know the boxer owner, and that she was just coming in to get water (not even a name was given). This is presumably a lie because its unlikely someone would let a complete stranger and their dog into their house. Also it seems suspicious that the homeowner did not give any helpful info at all, they were clearly withholding info.
The only info we currently have is the dog and the owner's descriptions.
What can we do in this situation? We are certain the homeowner is withholding information.
