Poor girl. Vomiting can be caused by so many things in dogs, but licking of the rear is usually caused by either full anal glands or intestinal worms. I would recommend taking Foxy to your vet to have her checked for underlying causes of vomiting (ie dietary indiscretion, kidney disease, pancreatitis, inflammatory bowel syndrome, etc), and then have her anal glands checked to see if they need to be expressed. Some dogs have a hard time getting expressing their own anal glands when they go potty, especially after a bout of loose stool, so we have to manually express them for them. This will relieve the pressure and discomfort. And the vomiting can be treated initially with an anti-vomit shot from your vet while you figure out the underlying cause and make sure to treat that as well. I hope that Foxy feels better soon! In the meantime it’s best to fast her for at least 12 hrs and offer a bland diet of boiled plain chicken and rice or cottage cheese for a few days to help settle her stomach. Best wishes and take care!
