Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

Has she only vomited the once?

Can she keep water down?

Are her gums pink or pale/white? Moist or sticky?

If you press on her belly, does she have any discomfort, tenderness, or tensing?

Could she have eaten something she should not have (ie bones, toys, plants, chemicals, etc)?

Has she had any diarrhea?

Thank you for your patience (as you can see I have been typing quite a bit for you),

First, I am glad to hear that she hasn't any discomfort, that you blocked her access to eating carpet fibers (since they can harm the gut) and that she has only vomited the once. That said, as she is quite young, we do want to tread with care. They can very easily become dehydrated or unwell when vomiting. This is because while a one-off vomit could be related to her eating too quickly or a mild dietary indiscretion, we can also see this associated with bacterial or viral gastroenteritis, pancreatitis, parasites/protozoa infections, and ingestion of harmful items (thankfully less likely for Sadie)

With this all in mind, as long as she can keep water down, we can try some home supportive care to see if we can settle her stomach. To start, if she hasn’t just vomited (since otherwise we’d need to rest her stomach for a few hours first), then you can consider treating her with an antacid. Common pet safe OTC ones we can use include Pepcid (More Info/Dose @, Zantac (More Info/Dose @, or Tagamet (More Info/Dose Here @
Whichever you choose, we’d give this 20 minutes before offering food to allow absorption. Of course, do check with her vet before use if she has any known health issues or is on any medications you didn’t mention. And if you try this and find her nausea too severe to keep it down, then that is usually a red flag that we need her vet to bypass her mouth with injectable anti-vomiting medication.

Once that has had time to absorb and she is steadier on her stomach, you can consider starting her on a light/easily digestible diet. Start with a small volume (a spoonful). Examples you can use are cooked white rice with boiled chicken, boiled white fish, cottage cheese, scrambled eggs, or meat baby food (as long as its garlic/onion free). When you offer that spoonful, give her 30 minutes to settle. If she keeps the food down, you can give a bit more and so on. As her stomach stabilizes, you can offer more. The aim of these diets is that they will be better tolerated/absorbed by the compromised gut. Therefore, it should get more nutrients in and result in less GI upset. As long as improvement is being seen, I usually advise that the diet be continued until her signs are settled, and that they are then slowly weaned back to their normal diet.

Since dehydration is a risk with vomiting in young dogs like Sadie, we need to keep an eye on her hydration. To check this and ensure she’s not becoming dehydrated, there are a few things you can test. Further to checking for gum moisture, you will want to make sure her eyes are not looking sunken and that she doesn’t have a "skin tent" when you lift the skin. To see how to check these parameters for dehydration, you can find a good video HERE ( If you are seeing any signs of dehydration already, then that would be our cue to have her seen before this becomes an additional issue for her (especially as it is often dehydration that makes them feel unwell).

Overall, a wide range of agents could trigger the GI upset we are seeing. If she has only vomited once, this may be a one-off and the above could be started to settle her stomach. If she cannot keep that or water down, appears dehydrated already, or doesn’t respond to the above within 12-24 hours (since she is young); then we'd want to get her vet involved. They can assess her hydration, rule out fever, make sure there is nothing in her stomach that shouldn't be there or any sinister viruses present. Depending on their findings, her vet can treat her with injectable anti-vomiting medication +/- antibiotics to settle her stomach, and get her back feeling like herself.

Please take care,

Dr. B.
