Peata also do this where you can go into hospitals/nursing homes etc with your dog so that patients who maybe are missing their own dogs can spend some time with them. I did this with my dog before (he was a lovely calm and sweet bichon frise). You have to pass an assessment with them to make sure the dog is calm and that you can control them. I used to go to an alzheimers centre with my guy and I have to say it was the most rewarding experience. The patients loved it and you could see the effect it had on them and the dog loved it too because he was getting loads of attention.
I would definitely do it again if I had a nice calm dog (my one now would just terrorise them 
).
Well done on planning to do it with Fraizer…hope it works out
