Dalmatians shed little tiny hairs all year long.
If I were you I would consider another breed, shedding is a very minor problem compared to some of the things you have to put up with this breed. If you do decide to adopt one, please take the time to research the breed very carefully. They are not a breed for people who have not had a lot of experiance with dogs and training. I suggest that you go to a good breeder and learn as much as you can and spend some time with some of theirs dogs.
