My dog has histoplasmosis. Can it spread to my baby or other pets?

Histoplasma is a fungus that can be found in the environment and specifically areas with bird and bat excrement. It is not generally spread directly from one animal to another, but certainly your other dog may have been exposed if they have been in the same areas. As far as human transmission, the biggest concern would be something like an accidental needle puncture with the organism, so your vet is much more at risk that your newborn. However, again there is concern if the soil in your area is contaminated. I think I would wait for the mass to be removed and to get the histopathology report on the mass to get confirmation of the disease, then start looking for possible locations of infection to try to prevent infection in anyone else.
I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.
