Hi Charlie and welcome to the forum! I'm in FL too but a little bit farther north in Brevard County.
That BB Wilderness is a great food so I wouldn't change if he's doing well on it. However, if you'd like other suggestions just let me know. There are several other really good foods out there.
If you feel like a road trip we will be having an awesome bulldog meetup with contests and goodies on July 29th from 3-5pm in Melbourne, FL at the Petco there. I'm not sure how long a drive this is for you, but it is lots of fun if you want to make some new bully friends.
We look forward to hearing lots more about Charlie and you!
