You're speaking with Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply. Please be patient. This may take a few minutes.
Susie, I usually fast these patients for a minimum of 12 hours following the last vomiting episode. Water should be left down if drinking induces more vomiting at which time ice cubes for Ludo to lick can replace his water. A simple dietary indiscretion such as ingesting "cattle muck" is certainly a reasonable consideration in such a young dog. In most cases such an indiscretion will remiss unaided within 72 hours of its onset. I don't treat these dogs as long as their appetite remains good and they continue drinking and so they're replacing their fluid and electrolyte deficit which arises secondary to vomiting and diarrhea. My "watchful waiting" period for remission doesn't last longer than 72 hours. If syymptoms persist longer than that I encourage caretakers to have their pets attended to by their vet who is likely to X-ray or ultrasound the gastrointestinal tract of these young dogs looking for foreign objects that may or may not pass unaided through the gastrointestinal tract.
Please respond with further questions or concerns if you wish.
