Dog antibiotics for kennel cough

Question
I adopted a dog from the ASPCA and he was sent home on Doxycycline . However after completing that he was still coughing and hacking. Mostly in the mornings and when excited. So I took him in and they prescribed Azithromycin  250 mg once a day for 5 days then one pill every other day for 5days. Is that common dosing in dogs? I know in humans antibiotics should be taken everyday for the whole prescription or risk creating a super infection resistant to the antibiotic . Is that not the case in dogs? Is every other day ok for them?

Answer
You still need to use all the antibiotics given. Azithromycin is made to dose this way so it's perfectly normal for the vet to use it like that.
While we have many things in common with dogs, how drugs affect them and us are totally different.

That is why so many things we can take are deadly toxins to dogs and cats.
