A. It is very uncommon for dogs, especially two dogs who live together to develop asthma. They can however have asthma-like symptoms and this can be caused by aerosolized irritants (i.e. hairsprays, house detergents, painting supplies, etc).
I would investigate and look for causes of irritation in the home. If they are found remove them and I would recommend placing each pet in a small room with an air purifier/humidifier to help clear the airway for about 30 mins- 1 hr for a couple times a day.
If there are no irritants to speak of, then it sounds like a follow-up visit with the vet is needed to further investigate other possibilities (possible re-check lung sounds and/or chest x-rays) of why your pets are still symptomatic and what appropriate treatment is needed to help them get better.
Also just to note that pets don't have to be kenneled or sheltered to catch kennel cough, they just need any close contact with other pets (such as pet-stores, dog parts, walks in the neighborhood). Kennel cough is highly contagious and is treated successfully in most cases with antibiotics, I like to use Doxycyline or Clavamox.
