When a dog is left with a groomer boarding facility, daycare, or kennel someone other than the owner may have custody and control of the animal. If that person or business knows the dog is aggressive and fails to handle or restrain it safely, liability can become an issue. In a serious attack, it is important to determine exactly who had possession of the dog and what they knew about its behavior at the time. I am Pennsylvania dog attack attorney Jeff Pennys.
