Hello. Yes, it is possible that Chula is dehydrated, or can become dehydrated soon. Not only is water lost each time she vomits, so are the electrolytes, sodium, potassium & chloride. The body requires us to take in & maintain a certain level of fluids, & even if there is normal urination & no diarrhea, we can lose fluids just breathing, & for dogs, panting. So, if Chula continues to vomit everytime she drinks, she will never be completely well & may get sicker. I would certainly recommend seeing your veterinarian as soon as possible. Thanks for using Petco Pet Education Center, formerly Petcoach.
