Pet's info: Dog | Pembroke Welsh Corgi | Female | 25 lbs

I have a corgi that is shedding more than normal. Today she threw up 4 times and her stool was runny. She does not have as much energy as normal. What could this be?

Diarrhea and throwing up can have many causes. It is basically a problem with the stomach and intestines caused by a food over sensitivity, eating something that does not agree with the dog, intestinal parasites, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Marley for 12 hours and then put her on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to her regular food slowly over a few days. If this does not clear up the diarrhea or if the vomiting increases, or if she gets lethargic, she needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.
