Maybe she took the dogs drugs?
May be on to something here. Last few years we had SCANDLE up here when 2 Vets in different states got caught making out RX for some elderly persons dog or cat that cost $5.00 and the same RX for a Human cost $125.00
Don't know how they were caught unless the Pharmacist noticed that they were filling a RX for Dog or Cat for pain pills every month for 18 years.
I can see the point of a Vet. feeling sorry for old folks and when it comes to medicine or heat in the winter, doing this for humanitarian reasons.
