Did they diagnose him w/an elongated palette? I had that surgery done w/both of my bulldogs, and I also had their nares widened... I DO believe it was lifesaving for my babies. My female Willow is tiny, and the vet stated that her pallet was the longest she had ever seen!!! I keep my house at 72-75 in the summer months. I keep fans going, but we have an A framed house so some rooms are cooler than others.
