Dog ate a face mask, now vomiting and lethargic. Is it an emergency?
Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Milo. Not sure if these signs are due to a possible ingestion like you describe, but I would advise getting Milo evaluated by your veterinarian as soon as possible. It is possible that the ingredients of the mask have irritated the stomach/intestinal lining causing these signs. It is always possible that the masque ingestion is just coincidental and other things are causing the signs.
The anorexia (not eating) and vomiting are very important though. Persistent vomiting and lack of appetite are emergent clinic signs due to fluid/electrolyte losses. This leads to dehydration, weakness, and further downward deterioration unless the vomiting stops and the appetite returns.
Many causes are possible including intestinal parasites, dietary indiscretion (eating things dogs aren't supposed to), other dietary problems, gastrointestinal inflammation/infection from various sources, toxin exposure, foreign body ingestion, GI ulceration, side effects from drugs or products used, or even problems outside of the gut including pancreatitis, liver/kidney problems, among many others. Your vet can get a detailed history and perform a thorough exam. Once done, a diagnostic plan and preliminary treatment plan can be started. Most likely a minimum database of fecal/blood/urine tests and some x-rays will be advised. Treatment will be focused on the cause but early treatment could include fluids/electrolytes, anti-nausea/vomiting medicines, acid blockers, etc. Good luck with Milo. I hope this passes soon and Milo bounces back to normal real soon.
