Hopefully your girl is still eating and drinking and still relatively bright. If she isn't then I really would encourage you to get your dog checked as soon as you can. The sooner something is picked up, the easier it is to treat. Too often my clients leave these symptoms too late before bringing their animals to me and by then too much irreversible damage has been done.
Whatever the case you should at least visit your Vet in the morning - unless she seems absolutely symptomless by then. Please keep a close eye on her mucus membranes, capillary refill time and respiratory rate tonight as follows:
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 appeal 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 blanced 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 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 she has ongoing lethargy tonight, seems painful or you are just overly worried about her state of health - ease your peace of mind by getting her to your local emergency Vet clinic. At the very least, please get your Yorkie mix to the Vet when you next can and request a full check up and blood panel whilst giving your Vet the full history of what has happened over the last few days. Best of luck with this little girl and please reply if you require any further info won't you.
