I know there is a list of dangerous medicines I plan to print out and bring, but anything else? Like precautions against false treatments (like skin scrapings and teeth trimming). My friend brought her pigs to the vet the vet told her one of them had a nasal infection (URI?) and that they needed 250 mg of vit. c a day which I think is correct. She also told her only to give fruits twice a week. She sounds pretty cavy-savy right? But still anylinks would be great.
