Is there a reason that your Vet gives Corona? It is not recommended much any longer…
That said, sounds like this has been going on for a while, but just got a lot worse last night. Have you talked to your Vet about his problem with loose stools with mucus? To me sounds like something is for sure going on.... Have they done a stool sample? Blood workup?
I do not know the reason, he just sent me the reminder that Nilo was needing his shots for bordetella, parvo and corona, so I took him.
Yes, I asked him about this on-off diarrhea and I asked if it would be necessary a fecal test, but told me that as long as Nilo was not vomiting while having diarrhea that there as not reason to panic, that I should keep an eye on him (he had not vomiting at that time).
Both things together just happened last night.
