Welcome!!!
Thank God for all of you. Im so glad that i found this site, im amazed reading all of your post, because i know people in my country that doesnt understand that you really cant predict how much your puppy is gonna weight when fully grown. Take for example my Fluffy, he's 4 years and one month ago his weight was 3.4 and yesterday his weight was almost 5 pounds. LOL
So, new friend just enjoy your baby and love him with all your heart.
