Dalmatians have a sad history of being abandoned or surrendered to shelters in large numbers after the release of each Dalmatian movie.
With each surge in popularity, backyard breeders and puppy-mills produce more and more Dals. To make matters worse, owners who got a Dalmatian on impulse realized that they are a high-energy breed requiring time and training.
Reputable organizations such as GotSpots.org have strict codes of conduct such as: "We screen potential adopters very carefully in order to find the best possible match for both you and our foster dogs. No Dalmatians will be placed into homes known to have intact companion animals, let their pets roam free, or have exhibited irresponsible care of current or previous pets.
All adoptions are expected to be lifetime commitments so please give this a lot of thought before completing an application. We will disclose all known behaviors, health or emotional issues to interested applicants prior to adoption."
