lol I was thinking something similar and waiting on that reply.
I'm just doing the maths here, did you get your dog as a pup in 2008? If so he's only 6, you have plenty of time left with him, our main stud is 11 in 2015 and we have 12 week old pups off him, there was 8 pups in that litter.
As for actually building your yard around this dog, only you can know the actual quality of this animal and weather or not he's worth building a yard around. Some pictures of the dog would be nice, for all we know he could have three eyes and two tails. It's hard to give an opinion on a dog just by looking at a pedigree, champions produce curs and curs produce champions.
Use your head and not your heart when deciding. Apart from being a great companion to you, what other traits does this dog posses to make him a worthy foundation dog for your yard and exactly what are you trying to achieve within your line of bulldogs.
