Welcome to JustAnswer...my name isXXXXX a licensed veterinarian, and will do my absolute best to assist you.
So sorry to learn about this problem. Do you know what medication your vet put her on for the vomiting?
That is good. Cerenia was a good choice, but why don't we hold off on it for a bit. You can give her the famotidine (Pepcid A/C) every 12 hours. How much does she weigh?
What did the tests show?
You can give her 10 mg every 12 hours. I also recommend withholding all food for at least 12 hours; you may already be doing this. When her vomiting stops, give her boiled chicken breast, turkey, or lean ground beef mixed with white rice in a 50/50 mixture; these should be very small meals 5-6 times per day. Then gradually wean her back on her regular food combining the rice mixture with her food.
Looks like she is also dehydrated; probably due to the vomiting. Can you get some pedialyte?
From a pharmacy.....
Are the gurgling sounds only when she is vomiting?
When are the gurgling sounds happening; when she vomits or all the time?
Does she drink the water?
But sounds like she vomits it right back up.
Has the vomiting subsided a little bit?
You should probably take her back to the ER. May be that she aspirated some of her vomitus into her respiratory tract and needs further treatment for that....they may have to keep her overnight.
That would explain the gurgling sounds.
May be she aspirated the vomitis after returning home from the ER. Did she have both vomiting and gurgling sounds when she went to the ER or just vomiting?
If the gurgling is very bad and she is in distress, you should return to the ER. If she is sleeping quietly it may be okay to just watch her removing food as both of us have recommended. Watch to see if the vomiting lets up and the gurgling sounds dissapate.
Do you have a thermometer you can devote to taking her rectal temperature?
How long has she been sleeping (without waking up and vomiting)?
I recommend just observing her; sounds like she is not in distress from the gurgling sounds or she would not sleep. If they get worse take her back to the ER right away. See if they diminish over the next day.
Water is fine if she drinks it.
You are so very welcome. Good luck with her.
