Hi and Welcome to YT! Congratulations on your new puppy!
He really should be seen be the vet, he may need to go on antibiotics.
I would suggest trying to borrow from friends or family... or you can apply online for Care Credit at:
CareCredit Veterinary Financing for Pet Care, Pet Surgery, Vaccinations & Other Veterinary Medicine Procedures They can approve you within seconds, and help you find a vet that accepts Care Credit as a payment. Some don't, so call to check before you head out.
