How long does it take for a Beagle to reach full-size?

I just got my beagle puppy a couple of weeks ago and was just curious how long it will take her to reach full-size.

by a year old she should be fully grown

Most dogs reach full height (Today’s Beagle comes in two height varieties -13 in. and 15 in.- and any true hound color), within 10-12 months, reach maximum adult weight by 18 months, and reach adult maturity by 2 years. (Just good rules of thumb, as dogs, even within their own breed, may vary marginally or extremely from this scale.)Hey - Beagles are great dogs, give them plenty or room to run & hunt...they're bred for it.http://www.akc.org/breeds/beagle/

What size Beagle???13 or 15 inch ?

about a year

like 6-7 years tops

I have owned several Beagles and around 8 months they are at their full height, although they will bulk up by a year old.
