...and show you proof of the bite If your dog bites someone and your not home how long by law can the cops take to tell you who it was your dog bit and show you proff your dog bite someone in pa

It is the bitee's word agains the biter. If someone fingers your dog, it's presumed guilty unless you can prove it was out of town. You will have to provide a rabies certificate, and if unable to do that, your dog will be impounded for observation for a few days.

They don't have to show you anything until you hit the court stage. At this point, your attorney can demand discovery which will tell you who made the complaint.As for proof, if there are no witnesses other than the victim, then that is it. My question is where were you when your dog supposedly bit someone? Did they break in your yard? Were they robbing your house? Dogs don't bite for no reason. They only bite because the feel threatened, protecting territory or they are hunting food. (the latter not an issue here)Get an attorney because US laws lean towards the victim.C
