Hi everyone, thanks in advance your any input. We have a person getting a puppy from us in a week whose older dog just came down with kennel cough. I am wondering how long they should wait before bringing the puppy into their home. I know that the dog can act healthy but still shed the organism. Would it be best to do an intranasal vaccine on the puppy about a week before him going to his new home. If so then how young can you start the intranasal vaccinations on a puppy? Also I know that after the intranasal that they can also show signs of infection and also spead it to other dogs/puppies. So what is the best course of action to take. Of course I don't want all the puppies to come down with it from vaccinating the one puppy. Also if I separate the puppy from the others then there is still a chance of them getting the symptoms no matter how clean I try to keep the house. Any advice would be great.
