Just thought I'd share this story in case it could help anyone in the future . . .
Yesterday, Shama threw up at about 12:30 PM. Then she heaved a few times without throwing up again. Then she started running around, snorting, sneezing, and wiping her runny nose on everything in sight.
DH washed her face in the hopes of removing the irritant, but she continued the snorting, sneezing, and wiping her runny nose on everything in sight. Then DH loaded her up to take her to the vet. (I wasn't home when this happened.)
It takes 15 minutes to get from our house to the clinic. Shama only had to wait about 10 minutes to be examined. Of the five vets who work at this small-town clinic (population 42,000 where we live and population 1,000 where we go to the vet and the groomer's), Shama's main vet was working, so that was great. She checked Shama's gums (looked good), skin (was dehydrated), bladder (empty), stomach (not seeming to be in discomfort), temperature (just over one degree higher than normal), and weight (8.3 pounds compared to the 8.6 pounds she weighed the last time we were there - the doctor said she was glad she was down a third of a pound). Shama was very good for the doctor, standing for her entire exam, not reacting to having the rectal thermometer inserted, and sitting for her IV. The doctor gave her some IV fluid to combat the dehydration, and she told DH that her guess was that Shama accidentally inhaled bile from the vomit and that the bile irritated her nasal passages. She was probably dehydrated from expelling all the mucus from her nose. She gave her an injection of Cerenia as well as two half pills of Cerenia for us to give today and tomorrow. We're supposed to only feed her chicken and rice through tomorrow. The doctor charged us for a sick visit, not an emergency visit.
We don't know what caused the original vomiting. She'd been to agility class the night before, and she'd eaten her supper after agility class the night before, but she hadn't eaten anything that morning.
Everyone in the online Havanese forum always says, "If something's wrong with your dog, take her to the vet right away." Even though this turned out to be a non-emergency situation, we were glad we took her to the vet.
Here's video from Monday night's agility class. (Sorry for the slow bit in the middle. Still working on start-line stays.)
