My pitbull is great but she poops in the house all the time even though I take her out, regularly. What should I do

How old is she?

Have you properly potty trained her?

Is she crate trained?

How often do you take her out?

When do you take her out?

Is she fixed?

She is three, she has been properly trained she is not crate trained and she is fixed. She goes out three or four times a day

Is this a recent issue, or has this been going on since you got her?

Also, how old was she when you got her?

Any changes in the house since this started?
