Thank you for your patience. Your Poodle boy's symptoms this evening are definitely a concern and the vomiting with blood clots could be a sign of a gastrointestinal bleed here. Possible causes for his symptoms include anything from a gastric ulcer, an acute gastroenteritis, a toxicity or poisoning, or potentially even an internal organ issue or blood clotting issue (to name a few possible causes here). You are going to need to continue to keep a very close eye on your boy overnight if you can. If he can't keep water down, then the concern is he will very quickly become dehydrated which will become the main issue here. If that is the case, then you will definitely need to get him straight down to your local ER vet now if you can.
Hopefully his vomiting has settled and he is able to keep water down now. Continue to with hold his food until the morning, but do encourage him to drink now. For now, you may also want to try him 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-pepcid
Continue to keep him rested and quiet. Please also keep a close eye on his mucus membranes, capillary refill time and respiratory rate as follows:
Mucus membranes - flip his lip and look at the color of his gums. They should maintain a nice salmon pink color. Get him 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 his 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 he is continuously panting throughout the night, this is a sign of shock and or pain and a signal for a trip to the emergency Vet.
If your boy is unable to keep water down, or if any of the parameters above aren't right, you will definitely need to get him to your local ER vet now. I hope all of the above makes sense?
