We have had therapy dogs in the ICU and even my new love was in the SICU ( surgical ICU) when he was cuddling with me.We have not had any increase of infections or other issues with the dogs being there and with a doctors notes even patients dogs can sometimes come in to visit them. I am sure there are people that feel the dogs should not be in the hospital but the vast majority of employees, patients and their families love the fact we do allow therapy dogs and the security dogs.
That said a few years ago my boss who was terrified of dogs did get bit by a new security dog
. He had gone down to the security office and no one was there but the new dog ( GSD) was wandering in the office instead of being in its crate. I think what happened next was the dog came up to him to sniff him and being afraid he made eye contact with it then raised his arms up fast and the dog jumped up and bit his arm and held on to it, It did break his skin and really freaked him out. It was sad as of all people for the dog to bite it had to be some one who was afraid of dogs. The other dog handler told me that the dog had not been doing the bite.hold so they had been working with it a lot to get it to do that..well I guess he wanted more practice
The dog was young and new and they decided to not keep it so traded it for a really great Belgian Malinois.
The security dogs do have to go through a lot as often young children will run up out of no where and hug them so that bite was just a freak thing form a young inexperienced dog and the fact the dog should have been crated when it was left alone in the office.Despite that happening my boss is Ok with the dogs being there.
