The adoption process is not always so strict. It depends on where you get the dog (or pet). I fostered three kittens for our local shelter a year ago, and they didn't even ask us on the fostering application if we had other pets or anything. We fostered all three for about 4 weeks and decided to keep them all. I don't even really remember filling out adoption papers for them. The lady knew us and knew we take really good care of the cats because they were so healthy and good weight, and we got all three for about $100 total (which included spaying/neutering and kitten shots). I think fostering is a great idea because you can have the dog and see his temperament and stuff. I always see lots of small dogs at shelters as well, many chihuahua mixes and stuff. Just keep an eye out... Check website listings of available dogs in your local shelter or visit the shelter yourself. Also, I can tell you want a puppy but I hope you have done your research and understand how much care and time puppies need. Puppies are cute, but if you get an older dog, a lot of times they've already matured (depending on how old they are) and usually have been housebroken already. Good luck in your future dog search if your parents let you get a dog!
