I definitely agree with Francesanne....I know that you posted early this morning, have you been able to take your dog in?
Also, it helps tremendously if you can share the age, breed, and any other important information about your pet. If this was a young dog, distemper or parvo might be top of mind, but in an older dog, seizures or a toxin might be more common.
Check back with us and let us know what is happening...
Hi, don't want to scare you but I'd get her to a vet asap. It might be something minor but it might also be Parvo. You must be worried sick and for peace of mind get her seen to quickly. All the very best and hope she's soon fit & well.
