but this is very dangerous. Please try,
in future never to forget to provide your
dogs with water, or access to clean fresh water.
They seriously can DIE of dehydration. Even in cool weather. A dog needs water every single day. Chronic dehydration can and often does, lead to kidney failure.
Keep an eye on your dog now, and make sure she is OK over the next few days. If she vomits again,or shows any other signs of illness, or unusual tiredness, please take her to a vet.
