My rescue dalmation, ZOE, was a handful at first but exercise was key in getting her to calm down. She was excellent with my kids, very protective of them but patient with them(i had been warned by many to be careful)
Beware of high protein foods with even a mix of dalmation as they are prone to problems dealing with the protein and this can manifest itself in many ways!
Early and consistent training is a good bet with any puppies, especially with the strong willed dals! I loved Zoe very much and she lived a happy 8 years with us(she came when she was 3). She was lovely and we miss her funny smile every day!
