My dog got infected with a cough and the soonest I can bring him to a vet is in 2 days.
- I know for certain that this is an infection but I don't know the exact bacteria / viruses that caused the infection.
- He is coughing and gagging and quite regularily coughing up white slime.
- He is eating and drinking as usual.
- He doesn't have a fever as far as I can tell.
What can I do to improve his symptoms until I can go the vet?
