Updated On September 23rd, 2025

Pet's info: Dog | Boxer | Female | spayed | 2 years and 7 months old | 70 lbs

Our dogs are coughing/hacking and sometimes vomiting clear phlygm. Otherwise they seem fine not lathargic, eating and drinking fine no weight loss.

This is likely an upper respiratory infection called Kennel Cough, this usually resolves within 2 weeks without treatment, but if the cough is too severe it is recommended to go to the vet in order to get cough medicine and antibiotics.
