My name is ***** ***** I am an experienced small animal veterinary surgeon, I will be very pleased to work with you today and will try my best to answer your question to your satisfaction.
How long has your dog had kennel cough for?
Hi I would imagine your dog has had kennel cough for perhaps a week or so because that would be the length of time for the normal course of drugs used to treat this disease. Normally a further course of drugs is not necessary since kennel cough is a mild and self limiting disease which will normally resolve on it's own in 10 days to two weeks whatever happens.
However if it does not continue to resolve over the next few days or if things get worse then perhaps you should see your vet for a further course of drugs.
I hope I have covered your question fully enough but if you would like further clarification or to talk things over a bit more then I will be on-line for the next hour or so and I will be more than pleased to continue working with you.Regards,Scott
