My dog throws up white mucus like the one you have during a cold, she sneezes and her nose is dry. She had a surgery 14 days ago and I'm giving her fluids intravenously. Could she has a cold or tracheitis? Thank you in advance

I'm sorry to hear Nana isn't feeling well. I would determine if she is vomiting the white foam, or if it is produced after a strong coughing fit. If it is after coughing it can be due to an upper respiratory infection such as kennel cough. If it is secondary to vomiting, then it could be due to a GI upset of some kind. I would recommend she be seen by her regular veterinarian to determine the underlying cause for her issue, have any necessary testing done (X-rays, bloodwork) and get started on any treatment she may need (antibiotics, cough suppressant) to help resolve the issue. Good luck!
