Do you know what she might have gotten into?

The best thing would be to take her to your vet to have her checked out and potentially get some radiographs to make sure there is nothing stuck in her stomach causing an obstruction.

A few things you can try now at home - you should remove food and water for 12-24 hours.

If the vomiting stops then you can try the following (if not then you should take your pet to your local vet or ER clinic)

1) One option would be a veterinary prescription bland diet called Hill's I/D or Iams Low Residue.

The second option would be a home-cooked bland diet. A common bland diet is boiled white rice and either boiled chicken, hamburger or turkey. Make sure it is boiled to get rid of any skin, fat, and bones that might be present. Offer the meat with mixture of boiled rice - 1/3 meat and 2/3 rice.

Initially only offer small amounts at a time -one bite every 2-3 hours as long as doing well then slowly increase the amount of food. Similarly, only offer your pet small amounts of water every few hours (so they don't gorge and puke after drinking too much).

If the diet is tolerated, and once clinical improvement is seen, it is recommended to SLOWLY transition back to the normal diet over 3-5 days

2) Famotidine (Pepcid A/C) 10mg tablets - the dose is 5mg for every 10 pounds of body Weight every 24 hours

3) You can also give pepto bismal. Give 1 tablespoon per 30 pounds of body weight every 8 hours.

I cannot stress enough that if this is not getting better, or you are noticing loss of appetite, lethargy, continued vomiting, worse signs of discomfort, or blood in the stool, then those would be indications to see your veterinarian for evaluation.

I hope this information helps! Please let me know if I can clarify anything for you - or you have other questions.
