If your pup is at Gulf Coast he's in excellent hands. We've taken our doodle there before and I can't say enough good things about them. Not just their level of expertise, but just the friendliness of the staff and how they run things.
Not cheap though. I hope Rover comes through quickly to help with the bills, so that it's one less thing you have to worry about.
We have a Bernese mountain dog puppy (8 months old) and had a Bernese in the past. Also have a Bernese mix and two goldendoodles. So we're well aware of the limitations of the breed. If we're available I'd be happy to watch your pup in a pinch if needed. I think it only helps if whoever your boarder is has a good understanding of the nuances of each breed. I don't know what I'd do if I lost any of mine while at a boarder's home.
Our girl can't be outside for more than about 10 minutes in this heat. Then she comes inside and sploots on the tile floor to cool off.
