hidden in the backyard grass, my 5 mo old english mastiff discovered & licked a tiny dead field mouse. diarrhea and vomiting ensued within 24 hours and has persisted. vomiting subsided after 1 day, replaced w/ dry heaves and abdominal rolling. diarrhea persists. she refused to eat or drink first 2 days. gave small amounts of gatorade via turkey baster to hydrate. now on chicken & rice diet. very small quantities to aid digestion. have metronizadole on hand from garbage enteritis from licking beneath outside garbage. gave first dose today while awaiting blood work results, which hopefully will be ok. agreed?
