Dalmatians are extremely loyal and loving. Dalmatians need to be part of the family. They want to sleep in your bedroom, follow you from room to room as you move about the house, and spend all their time in your company. They are extremely devoted and but without proper socialization and training can become territorial. Nothing can match the look of adoration in a Dalmatian's eyes when he looks lovingly at his human.
Dalmatians are high energy dogs.
This does not mean an owner has to be a marathon runner or provide a Dalmatian with a 50 acre backyard. It does mean they need regular exercise such as several long walks a day or some time to play in a fenced yard. However, they are also not backyard dogs. Dalmatians are very intelligent. They do not do well when left to grow up with no training.
