I love Daisy shes adorable. I have a 1 year old boxer He was a rescue from anothe Pet talker. He was abused and was very thin also. looking at the muscle tone on her front . I would say she's still a very young girl. How old is she.? It could be she's just a pre teen and they some times look that way . Boxers don't get tired so they burn off evey thing they eat.
I hope you are ready for a lot of exercising and playing if you have never had a dog before you are in for a lot of learning and work. Boxersare a very high maintanice breed. I just had a 6 foot cedar fence put up and Tyson will jum froma stand still to hook his paws over the top and watch people go by.
I would suggest you " Boxers for dummies "at your local pet or book store.
I have raised dogs for 40 years (mostly spaineils) boxers are a totally different expience . I love him to peices ( which is what most of my lawn furnyure is now) But if bored they will be destructive, keep lots of toys and keep her busy. Get on the obediance training NOW as they are Very strong dogs as they get older.
They are a soruce of eternal amusement also. If you want to se some of what i mean look up threads labeled Boxer shorts by me or Dugansdad (my hubby ) they will be in dog general. enjoy your sweet heart.
