Q. Why would 6-month female Rottacollie (normally in and out of doors) be vomiting last couple of days? And just started with diarrhea? Licks self more?
DAVID ELBEZE, DVM, MRCVS
A. She could have a gastrointestinal infection from something she ate. If she is not vaccinated she could be infected with parvo virus which can be very dangerous and life threatening.
Other conditions like a foreign body in the stomach or pancreatitis are also possible.
I would advice to take her to your vet ASAP as she can get dehydrated quickly with the vomiting and the diarrhea.
