Owner passed away - Rehoming another dog (St Charles)

A friend of ours lived with us and had two dogs. She passed away in May. We have applied with a couple shelters to rehome the dogs. Believe Biscuit is about 4 years old. We did have two other dogs, four total, and Biscuit was fine with the other dogs. Nominal rehoming fee to validate interest. Shots are not current. Biscuit is neutered.
