My dog's severe diarrhea won't stop after home remedies. When to see vet?
If the diarrhea has been going on more than 24 hours and Lj hasn't improved with bland food, probiotics, and Immodium, then it's time to see a vet. There are many possible causes of diarrhea: stress, dietary indiscretion, infection, parasites, and more serious issues such as inflammatory bowel disease, Addisons disease or cancerous changes. You've done a great job trying the simple initial interventions that can help - but if that didn't do the trick, then it's time to have Lj checked out. Hopefully it's still a simple cause that will respond to a course of medication, but sometimes further diagnostics or long-term therapy are necessary.
Your vet will likely recommend starting with a fecal sample check to look for microscopic parasite eggs. Depending on exam findings, they may also recommend some initial screening bloodwork to evaluate general body function and help screen for some of the conditions that can be associated with diarrhea. Or, they may recommend an initial course of medication to see how Lj responds and go from there.
Hope this helps!
