Hi Janine--
Congrats on your new puppy...As for her size...I dont know if you can truly determine that...Sammi was 2.5 lbs at 14weeks, she is now 13lbs...So that formula, double the weight @ 12 weeks old didnt work
As for Puppy Paradise, PLEASE PLEASE take your pup to YOUR OWN (not the vet puppy paradise recommends) vet ASAP...In my opinion, that place get their pups from mills...They have way too many breeds...and the whole "Rent-A-Puppy" for your party thing...TOTALLY AWFUL...Just please bring her to the vet
Please feel free to PM/EMAIL/IM me with any questions...
Thanks!
Fran
