Hi again,Thank you for your patience. As you can imagine, there are a number of possible causes for Chloe's vomiting today including anything from an acute gastroenteritis, intestinal worms, a toxicity or poisoning (hopefully there isn't anything around the yard she could have gotten into), or even an internal organ (although this is unlikely given her age). Hopefully she is drinking well and able to keep water down, otherwise she will very quickly become dehydrated. Keep an eye
on her hydration status if you can (it sounds like you know how to do this). For now you can with hold her food until the morning. From then you can start her on a bland diet. For this, cooked, boneless skinless chicken
breast and boiled white rice is fine. Also make sure she is up to date with her deworming treatments and be sure to use a reliable product for this like Drontal
or Milbemax. You need to encourage her water intake now if you can, and hopefully she is drinking with now issues and able to keep water down. If she can't keep water down, then you need to get her seen by your local ER vet now so they can keep her in on IV fluids and give her an antiemetic injection to stop the vomiting. If you can, please keep an eye on her mucus membranes, capillary refill time and respiratory rate tonight as follows (do be careful that your girl doesn't try to bite you):Mucus membranes - flip her lip and look at the color of her gums. They should maintain a nice salmon pink color. Get her to the emergency Vet if they appear white or very pale pink, or if they are a dark deep red color.Capillary Refill time - this measures blood perfusion and test this by putting your thumb on her gum to apply pressure. After you release your thumb you will see the gum blanch. Capillary refill time is the amount of time it takes (in seconds) for the gum to return to a healthy pink color from the blanched white color. If 2 seconds or less don't worry - if it is taking significantly more time, again - off to the emergency Vet.Respiratory Rate - if she seems to be panting or breathing rapidly throughout the night, this is a sign of shock and or pain and a signal for a trip to the emergency Vet. For now, you may also want to try her with a little pepcid. The typical dose for this type of situation is 0.25mg per pound of body weight up to twice daily. You can read more about the use of Pepcid in dogs online here: http://www.petplace.com/article/drug-library/library/over-the-counter/famotidine
