Well, I don't see why you posted about this at all. What do you want from
us here at PT? Do you wanted to be reassured you are doing the right thing?
I really would like to know what we can do, other than the advice already
given re: training, making Daisy a real part of the family from the very start
would have solved many of the problems you are now having with her.

Like I said, you have your own opinions about the proper way to raise a
dog, and now are living with the consequences of your choices. What do
you want to hear from any of us?

If you do rehome Daisy, please, please contact a Boxer Rescue group. They
are full of people who know & love the breed.
