Jan look around in your area for some Organization that can help you get the dog shots and help get the dog fixed if it isn't already.

Also if you PM me with the state you live in and you feel comfortable with the city include that. My daughter has been working at petsmart and they really like her and she really likes it they promoted her to dog trainer and paid for her classes and certification. If there is a pets mart near you I can see if her GM can reach out to you or knows of some place in your area. No guarantees but I will ask her for you
