Hi,
The UK breed standard says that dalmatian bitches should be 22"-23" tall (55.9 - 58.4cm) and dogs 23" - 24" (58.4 - 61cm). Though many dogs are unfortunately getting too tall.
The males are no worse, and better than some, other breeds for getting on with other dogs. Though they aren't the easiest of breeds to train, and need careful handling and plenty of socialisation.
