Please help me save my dog

Hi guys, thanks for taking the time to hear my story. I would really appreciate any help. My dog lightening has been the joy in our lives and the other half of our duo thunder and lighting since he was 6 weeks old. He’s nine months and inseparable from my daughter. He’s had a perfect bill of health until we had a small gap between vaccinations and unfortunately has been diagnosed with Parvoviruses. I would do anything for my dog so I’m taking a small leap of faith and hope someone sees this and if you feel like helping I would be more than grateful. We’re in the process of talking out all our options, I just want what’s best for him.
