Not really, aspergillus stays contained in the sinuses of your dog and it also needs certain conditions to thrive in those sinuses, as well as a compromised immune system of the dog. Aspergillosis can be treated with flushing the sinuses with a fungicidal wash. In order to do so, your dog will need to be sedated and in most cases the vet will have to make an access ( trepanize a hole) through the bone above the sinus. This is a bit complicated but doable and the fungus can be killed off that way. So again, no, it is not possible to directly transfer aspergillosis from one dog to another.
