He urges caution. If they want a Dalmatian, I ask them if they have a one-acre fenced yard. These dogs are very hyper, very energetic, they don't become good house dogs until they are four to five years old. A full-grown dalmatian weighs between 40 to 70 pounds. Dalmatians have historically been bred to trot all day with a horse and carriage.
Dalmatians can take two to three years to mature mentally.
They have a unique uric acid metabolism, which can make kidney and bladder stone formation a possibility. Most Dalmatians are very active and if they are ignored or not exercised enough they can become high strung. Obedience training is extremely important so the Dalmatian learns boundaries and what is expected. And, there are other problems. Hereditary deafness runs in Dalmatians.
