Thank you everyone for your wonderful advice! It is very difficult finding a place to board around here. Hence why she's been to so many different barns. It seems like people have good intentions until they see him. He's big, that's it. But, his size scares some people.
Anyway, a new barn has been found! The best thing about this new barn is that it is at a dog boarding kennel where my daughter works! Her boss has some horses and she said she'd be happy to have him there as long as she helped with his care and cleaning other stalls. My daughter is thrilled at this idea!
Now all she needs to do is to learn how to drive!
Cause this place is a half an hour drive away and I really don't want to make that trek on her days off.
