Well...I don't know what an adult/elder puppy would look like...a wrinkly baby? Lol! But yeah, I know what you mean XD That's 5 stages total, and just a little bigger than those older pieces. I can start tomorrow or Monday, since I'm going to be busy today...and, no need for references, I have it covered.
Oh, and good luck with your puppy! She's adorable!
