Welcome to the site and I don't know of any in the area but check out the web site that [MENTION=2894]2BullyMama[/MENTION] suggested to see if you can find some. We would like the see some pics of your babies also. I will tag [MENTION=3247]acarabias[/MENTION], she lives in El Paso and may know of a group there.
I'm in the McAllen/Mission area, a couple of years ago there was a Bulldog Club here, however, I believe it kind of went by the wayside. From what I've seen San Antonio is the closest place with any planned activities.
