How big will my puppy get?

[freckledimple]

I have a new puppy. He was dumped at my neighbors house and they gave him to us. We took hin to the vet and he said we have a healthy 13 lb 3 month old. There was no mention of what he might be, or how big he'll get. I was wondering if anybody had an idea on either of those issues.

This is our JD.

He is sooo cute! Congrats.

He looks like he might have some ACD in there. (Australian Cattle Dog). He'll probably be medium sized. Doesnt appear to have very large paws. Im no expert though, thats just my guess

He will be 30-40 lbs. most likely. The reason I say this is that a Brittany puppy (which grows to 30-40 lbs) is about 12-15 lbs. at 12 weeks.
