I’m Getting A New Puppy, But I’m Not Sure Of How Much It Will Cost To Care For It Overall.?

It will, because of my allergies and mother, most likely be a toy dog breed. I might get a Havanese or Malti-Poo or Shih-tzu, or a breed in the Bichon family. It will definitely be a puppy, and I’m going to crate train and possibly litter box train because it will be so small. So if any of you could give me a general overview on what i’ll need to buy and price ranges and things like shots and what not. And also what I should look for when I find a good offer on a puppy? I have no idea what CKC and AKC registration are.
