Mia was supposed to be a border collie puppy. I decided to get a papillon puppy instead for a few reasons. 1) At the time I was moving around a lot and renting apartments. Mia was more portable and I had a lot more rental options. 2) Mia and Summer are the same size and I do think that is MUCH easier to handle. You can handle multiple sizes but I love that mine can play and I don't have to worry. 3) Summer is a little DR and she gets on better with puppies than adults. Adding Mia was a breeze and she's the best dog I've ever owned. My dogs get along great and are easy to take places together. It all worked out perfectly. My next dog will be bigger and a puppy. I'm settled into a place and job I can see myself in for a long time. I have a yard now. I'm not moving although I am saving for a house. I have two good training places I'm already established with and already know what classes the pup will take. I finally have enough income to comfortably take a bunch of classes and get a dog walker and not feel crunched. since getting into dogsports there's things I want to try with a bigger dog now. I also want a puppy I can implement all the new sports training knowledge I now have on. I'm super excited about that. Raising Mia was a blast and I love molding an eager and bright little pup into a good dog. I never want a BIG dog. Medium (bc/aussie sized) is as big as I will ever go. not a good fit for what I want to do and just not many big breeds that really interest me.
