Why can't I take my dogs to hospital?!!!

having worked in long term care and in visiting nursing for over 35 years, I can definitely say visiting pets are a form of good medicine...anyone who would even want to take a pet into a hospital/LTC would already be caring enough to make sure the animal was bathed, needles up to date, well behaved etc...they would not be bringing in street dogs ! The wees made visits all the time to ill people and they never failed to bring a smile to someones face..my Bella was especially good with ill people and I have even had doctors mention to me that Mrs or Mr so and so could do with a quick visit from the wees...no one ever caught anything from them nor did they contract any deadly bugs. It certainly made my decision to let the girls do visitation be validated over and over when I would see someone within days of death, resting peacefully while slowly petting one of the girls...there will always be people who feel this is wrong but it wont be the one of the patients.
