he is a slighltly larger pup (judging from the weight you said) but it just means there will be more of him to love he's extremley cute I still cant gage his size a coke can is usually the universal size indicator lol. If you find out the weight of his dad it would give you a rough idea of his possible size, was he still one of the smallest in the litter when you went to go collect him or did he catch up with the others?
He was the smallest when born, but he soon got bigger, and was one of the biggest i think
And when i take him to vet, ill then get a proper weight reading hopefully
His dad was so petite and tiny, not sure on his weight!
all chi's look petitebut from the photo I saw of the parents they werent exceptionally small and is often deceptive if you're not used to seeing them sooo I'd try and find out the weight of the dad as it's a good indicator, Nemo & Zero's dad was only about 2 1/2 -3lbs so thats why they're both on the smaller side eventhough Zero was the only pup in his litter.
