To the OP - lots and lots of obedience training - right from the start.
If you haven't already, read up on the breed info.
They are people dogs, which can be good and bad - good that they like you, bad that they like you so much that they act out while you are away, destroying the house.
Also, in my experience - they tend to be barkers.
From our friends at Wikipedia.
A large number of Dalmatians end up in shelters and rescue homes, often being stated as being difficult and un-trainable. A Dalmatian being un-trainable is not true; it is more a problem with the owner's inexperience with dog psychology, dog training, and/or lack of information about the breed than the dog itself (this statement usually holds true in most cases, irrespective of the breed of dog).
Dalmatians have extremely sensitive personalities and will not forget ill-treatment. Ill-treatment can and will break a dog's spirit and a Dalmatian's - certainly so.
While a Dalmatian with a clear rank idea, proper and correct obedience training, would make an excellent companion for anyone or any sized family, Dalmatians are not a breed for a first-time and completely inexperienced owner, especially one whose expectations of the dog and its behaviour are high, especially in terms of obedience or those who have little time and patience to train them.
While a desire to please their owners can be a taught behaviour, they do not have a natural desire to completely please their owners in comparison to some other breeds, e.g. shepherd dogs. Generally speaking (and specimens may vary) Dalmatians are a rambunctious, playful breed and usually seem to have a mind of their own, which makes them more challenging to train and requires more knowledge of dog training. Generally speaking (i.e. individual specimens may vary), their attention spans are limited. More so in the hands of an inexperienced owner who does not create the correct rank order. Combinations of rewards (treats, play and praise, in that order) are your best bets and will go a long way in getting their attention and for training purposes [please note the difference between rewards and bribes].
