Bulldog Rescue
It's important to buy from health checked parents to avoid any heartache in the future. - It's worth speaking to an experienced owner/breeder to ensure you know which tests should of been carried out on this breed.
Have you thought about rescuing an older dog - I've posted the link for a British bulldog rescue.
Or how about a shih tzu, they have a loving temperment and have been bred to be a companion so do not need tons of exercise. Their fur does grow long so will need to be taken to the groomers every couple of months to have a hair cut.
