My Harley dog is vomiting a green phlegm?? I have an 8 year old male yorkie I have had since birth. He gets fed once a day a dry lamb and rice mixture, has good elimination regularly, exercises daily and is not up to date on his immunizations. This morning he vomited a green phlegm like substance. He doesn't appear lethargic, his gums seem to be good in color and refill, is drinking water fine, gets a monthly flea/tick/mites meds between his shoulder blades on the 5th of every month. WHAT could this possibly be? |
