Very informative. If ever I am to choose a pet, i will prefer having a dog also. Like what you said, dogs are sweet and loving. And very smart as well. Anyway, I want to add some info, not quite sure if this is true. I just heard that a single year of a dog's life is equivalent to 7 years if converted to human age. So if your dog is already 3 yrs old, she must be 21 at the moment. 😊
