For my dog’s medicine

My puppy has been having cough and weakness since a month ago. Normally I can afford to send him to the vet, but I had to stop working because I was about to go abroad for employment, then the lockdowns and restrictions happened, and I found myself unemployed with a sick puppy. I cannot afford to have him adopted, he's my buddy. Please, help me help him, I can only do so much and now my finances are dry. Any amount will do and is greatly appreciated. Thank you so much.
