NO LOCAL VET

Had to make a new post because since people kept telling me to bring him to a vet. The nearest vet is either 12-14 hour drive depending on the highway, or a 3 hour $1500 flight to the nearest city. We can't make that travel on short notice. My boy Jackson, roughly 10, maybe going onto his 11th year got an abscess a few months back. We did get him on antibiotics but unfortunately that didn't work. He us now starting to show he is getting weaker by not eating as much and not wanting to go on our daily walks. Will the hospital help us in this case?
