Female Boxer 5 yrs old (Great Falls)

We are looking for a good home where our female pure bred boxer can run and play.
She was born Sept 11, 2018.
She is very friendly, loves kids and other dogs.
We love her but she is not a good fit for our neighborhood.
She does not come when called.
She is very social so wants to go and see what the neighbors are doing and gets excited to play with neighborhood kids who are afraid of dogs.
She has gotten into chicken coops and attacked chickens.
She really needs a home where she can run and play in the country, would work well on a farm/ranch.
She does very well in a vehicle and on a boat.
If interested, please email or text.
