hi, i have wormed my puppy again and she has a "hacking" cough. can this be linked to worming? she has been perfectly healthy up till this coughing. she is still playing and eating.

Has she met other dogs? Sounds more like it could be kennel cough.

she has been vaccinated, would that not cover kennel cough?

Only if she had the special kennel cough vaccine, that's squirted up the nose, not an injection. It's not one of the 'core' vaccines, so is optional.
