There are so many different breeds of dogs so it is kind of impossible to not find the right kind of dog for you. A dog is considered to be human’s best friend out of all animals. In total there are about 400 million dogs in the world and a dog average life span is about 10 years. Now 10 years is not a long time so let’s say if you get a dog for your kid at age 10 so by the time your kid is 20 that dog is going to be in its last stages which is really sad. Please see below for some of the best dog coloring pages.
