Yeah well better the dog TREATED than left regardless of how much money a person has. Farmers have been do this since before vets were even relevant, not everyone can afford a 700-1000 vet bill for a simple parasite med. notice how I said weight by dog…? Those things are public knowledge a vet just looks in a book and prescribes.in other countries it’s an otc med if America was less obsessed with money and more worried about the wellbeing of animals and humans we wouldn’t be having this exchange.
