When I was 13, I was kinda in the same boat. We had T.j but he was my dad's dog. I wanted to show a dog, and T.j never really bonded with me like my he bonded with my dad(my dad also didn't want me to show him). It was really upsetting. T.j was more like a one person dog before we got a second dog. Seeing I was really upset and a natural dog lover. My parents let me buy Zoey. I naturally did all of the grooming (bathing, clipping nails and hair), picking up poop, and vacuming. After we got Zoey, T.j became more open and not a one person dog. I wish I could have adopted, but I wanted to get really heavy and showing. So it was a lot of money for me to pay for the price of the puppy, vet care and all of the supplies. So yes I agree adopting will be a lot cheaper and if I do say so myself, the dogs that come from shelters are one of the best dogs.
