First, I am glad to hear that she hasn't had any of those more serious signs I asked about. As well, just to note, if she has vomited up food then we'd not be overly worried about fecal decline at this stage (since little input leads to little output). Now despite her signs starting after the groomers, if they did not give her anything, then this is unlikely to be related to that visit. There efore, we'd have to be most wary of a coincidental bacterial or viral gastroenteritis, pancreatitis, parasites/protozoa infections, general dietary indiscretions, and ingestion of harmful items (hopefully less likely at her age).
With this all in mind and since she has only had the one vomit, I would suggest trying her with supportive care at this point. To start, since she can keep water and that bit of rice down, we can initiate our care with an oral antaicd. Common OTC pet safe options would be:
* Pepcid (More Info/Dose @http://www.petplace.com/article/drug-library/library/over-the-counter/famotidine-pepcid)
*Zantac (More Info/Dose @ http://www.petplace.com/article/drug-library/library/over-the-counter/ranitidine-hcl-zantac)
* Tagamet (More Info/Dose Here @http://www.petplace.com/article/drug-library/library/over-the-counter/cimetidine-hcl-tagamet)
Whichever you choose, we’d give this 20 minutes before offering food to allow absorption. Of course, do double check with your vet if she has a known health issues or is on any medications you haven't mentioned.
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. Besides the rice, consider adding in a protein source (ie boiled chicken, boiled white fish,cottage cheese, or scrambled eggs, etc). Or there are also OTC vet diets that can be used (ie Hill’s I/D or Royal Canin’s sensitivity) too. 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 continuing this until the signs are settled, and then weaning her slowly back to her normal diet.
Since dehydration is a risk when we have vomiting in older dogs, we need to keep an eye on her hydration. To check this and ensure she’s not becoming dehydrated, there are afew 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 for dehydration, you can find a good video HERE(http://www.ehow.com/video_12232503_dog-dehydrated.html). 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 and lethargic).
Overall, there are a wide range of agents could trigger this GI upset we are seeing. Therefore, we’d want to start supportive care to settle her stomach. If she cannot keep that or water down at any point, appears dehydrated already, or doesn’t respond to the above within 12-24 hours (since she is older); 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. As well, with her age, you may want to also have them check a geriatric blood sample to make sure her organs are working as they should. 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.
I hope this information is helpful.
