You need to cut the behavior out. If she is misbehaving, then that is it, the walk should automatically be over. If you immediately take her home and put her away as soon as she acts up, she will soon learn her bad behavior has consequences.
A family friend has recently been thinking of breeding. I did some research and found this article that I was thinking about sending her. http://thedogbreedsbible.com/long-dogs-pregnant/
Would anyone be able to verify that this information is correct? I would greatly appreciate it. Thanks!
