I come across decent pups from time to time. If I know of any around your range in LA I'll post it here.
Good luck finding one for $1500. They are rare especially if you are wanting quality. You have to be careful when you find that good price as they often are accompanied with many of the health issues Bulldogs are at risk for. I know someone who found one for $1600, but the poor thing has had skin problems, cherry eye and diagnosed with hip displasia at 6 months old. Although these are common and something that can come with any English Bulldog multiple issues are usually stemmed from poor genetics and subpar care right after birth. What you save up front on price will cost you double in the vet bills you will inherit.
