Yes! Sunshine exactally develop energy ,and this dog is black in color,and according to science black color absorbs the heat energy more than any color.....in Indian religion black dog is dedicated to the Planet "Saturn" .It is said that having a black dog and taking care of it makes Lord "Shani" happy.......and then it gives +ve energy to the regading ! So I also like black dog,not only black but in real I like all the dog and usually provide some bread and jaggery to them whenever posible!!!!!!!
