As we tend to do from time to time, we were searching craigslist for Boxer postings, when we came across a post listing a "Mini Boxer" for sale.
THERE IS NO SUCH THING AS A MINI BOXER! Please do not be fooled by ads saying there are.
There are smaller Boxers (usually from health issues/trauma as a pup), but there are no "minis".
The one we saw on craigslist says it is 15 pounds, at almost a year old! This is a MIX, a mutt, a cross, NOT-a-Boxer ... usually Boston Terriers x Boxers, OR some are actually crossing the Rat Terrier with a Pug, and calling it a Mini Boxer.
