Thank you again,
* I am here, but as you can see was in the midst of typing for you*
First, based on the signs we are seeing, we do have a few concerns. The most common cause for her signs is a severe pancreatitis. Though we could also this (especially if she is severely sore) with gut twists, gut blockages, or if she has eaten something harmful. Bloat can also appear this way, but is uncommon in her breed.
With this all in mind, if she is so sore that she is yelping (though thankfully her breathing rate isn't one of distress), I do feel it would be best to have her seen now. Her vet can make sure the gut isn’t compromised and that there is nothing harmful causing damage. If those can be ruled out, they can start her on strong injectable dog safe pain relief +/- fluids, antibiotics, and gastroprotectants as needed.
Though if there is any delay in having her checked, I’d note that you could at least consider starting her on an antacid like Zantac (More Info/Dose @ http://www.petplace.com/article/drug-library/library/over-the-counter/ranitidine-hcl-zantac) or Milk of Magnesia (0.5tsp every 8 hours). This will reduce nausea and protect the stomach if there are any ongoing ulcers. 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. As well, 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.
Afterwards and if she settles, we can try to tempt her to eat with 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). There are also OTC vet diets that can be used (ie Hill’s I/D or Royal Canin’s sensitivity) too. 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.
Overall, all of Abby's signs are ones that suggest pain and nausea; which would raise the aforementioned concerns in her abdomen. If she is so sore that she is yelping and cannot put pressure on her abdomen so she can lay down without pain; it'd be ideal to have her seen now so that we can get to the root of this and get her comfortable as quickly as possible.
Finally just to note, all our practices in our country will have contingency plans for out of hours urgent situations. Therefore, do ring the practice now and there will likely have a message to direct you on how to contact their out of hours service. And if you don't have a vet you can find a local one via the RCVS Register (http://findavet.rcvs.org.uk/find-a-vet/) or Vets Now (http://www.vets-now.com/find-an-emergency-vet/ ) who are open all nights/weekends. In any case, there are options to see a vet locally today too.
