Dog gets kennel cough twice in a month?

I have a 7 month old English Bull Terrier who received all her vaccinations on time. Last month our boss brought his dog into work and mine was there too and both dogs were playing in the back office. I heard the other dog coughing and I ran to the back worried it was choking on something. It sounded awful. My boss was there and said that it had been having coughing episodes quite a bit that week and took it to their vet that evening where it was determined it had kennel cough. 3 days later my puppy came down with kennel cough. I called my vet and told him what had happened and he prescribed me an antibiotic and a cough suppressant. My puppy took the 10 days of antibiotics and we kept her calm and away from other dogs for 2 weeks. After that she was back to being a happy go lucky dog playing and being a super hyper dog. Now, last Friday she woke up with the same honking cough she had before. This time it was so extreme it was causing her to gag and throw up some bile or pieces of recently eaten food. I called the vet right away and he was out for the week but they prescribed me the same meds and I got her started that morning. Her cough is 95% better and only occurs when she get all wound up. I have an appointment this Wednesday to have a full checkup done as soon as my vet gets back into the office.

I am really concerned that she contracted kennel cough again so soon. From everything I have googled, this doesn't seem normal. And the bad thing about googling is that I find so many other possible things that could be wrong. She is eating, drinking, pottying and everything normally. It is really hard to keep her calm and not let her get too excited but we do the best we can. I have had her on probiotics and enzymes since the first time she was on antibiotics to help keep her immune system healthy. I am doing everything I can, I am just so worried :(

Any help or advice would be greatly appreciated. ThanksDog gets kennel cough twice in a month?
Wash everything she gets around. Her bed would be the first place to start. toys put in the sink or bucket with a little bleach to kill everything on them also. Its very likely that she is getting it from these things.Dog gets kennel cough twice in a month?
I would keep her away from other dogs until she's completed all of her treatment and has been symptom free for at least a week. Kennel cough has more than one strain, and the often administered intranasal vaccine isn't for all of them. So even if you have your dog up-to-date on vaccinations, she could contract the illness.Dog gets kennel cough twice in a month?
wait for the appointment has she been given bordetella this is for preventing kennel cough often vets don't give this as a regular vaccine it is something needed to be asked for separate

if she hasn't had find out about getting her the bordetella

also would not let her near any other dogs for at least 1 month after totally cured to give her iimmunesystem to build back up
I dont think you need to worry that it is something else. Kennel cough sticks around for a long time. Your pup was getting better with the first round of antibiotics but needed to stay on it longer. That coughing can last a month or more. If you have a humidfyer set it up for your pup. It helps a lot. If you dont have one I would go buy one. If you add the vicks into the machine it really help. As a last resort take your pup into the bathroom and run a hot shower for the steam a few times per day.
