Gastroenteritis in Dogs
i am still concerned as gastro is in fecal or vomit but you stated she was bleeding from the vulva correct? If so i am still concerned about pyometra as someone else on here her dog was not diagnosed properly and vet thought her dog was pregnant when in fact she had pyometra and she was adimant to spay her immediately and it turned out when he opened her up she had pyometra and was not pregnant as owner was adimant no way she was pregnant so due to owner being adimant her dog was saved.
Let us know if that bleeding was from vulva as no way would a gastro intestinal upset come out the vulva and many times vets label anything intestinal gastro intestinal
was her white blood cell count high as that is signs of infection
if no blood from vulva then yes this could very well be gastrointestinal and hge as you desribe vomitting is blood clot as the diarrhea and vomit is clotted when hge and it is very dangerous as the red blood cells multiply shutting down the organs and can be deadly if not treated immediately
