Great to hear you have a pup on the way! My French Brit story is that I great up hunting with country raised Brittanies. My city girl wife bought me a pup for Christmas, he was black, I didn't even know French Brits existed, and found out all I'd ever known was American Brits. I thought he developed dysplasia at about 1.5 years old. Limped bad the rest of his life when running much or in the field. Shame to, he had some great natural ability, but never really hunted him much after that. Would put him out when driving around the ranch and run across a covey of Bob's (This was in the early 2000's when we actually still had birds in our part of Texas.
Anyway, the point is, later I found out that he probably didn't have dysplasia, I probably actually accidentally ruined him, in my ignorance. I reasoned that a country dog ran around all the time, so I, now living in the city, should run him alot, which was convenient since I was training for a marathon. I know now that they say you shouldn't run a pup like this until at least after one year and better up to two years. I have waited since with all of my pups and had no problems. You probably wouldn't have made this dumb mistake like I did, but thats a story to consider. Best of luck with your pup!
