my mother's cocker started having diarrhea & vomiting yesterday. she wouldn't eat anything. today she ate some cooked rice, hamburger and boiled egg (my vet's recipe) but is still having mild diarrhea. we haven't seen her drink much water today either. I think she is better today but my mother is ready to rush her to the emergency vet. It is also 100 degrees today and the dog hates the heat. do you think a trip to the vet is necessary today or if she isn't better tomorrow take her?
