Boxer Puppy Wanted

We would love to have a female boxer that would be at least 6 months old. We live in Helsinki Finland, and we have had boxer dog before. He died at the age of 11 years. We love dogs, but do not want to raise a very young puppy. We live in a house with a big garden and we love hiking and being in the nature. If anyone knows breeders that could have an adult female boxer or about 6-12 month old boxer, we would be the happiest owners !
