Let's get @2BullyMama...@Sherry...@Davidh....@Vicaroo1000... @Vince...@cali~jenn
What we have done when dealing with a female Rottie and dominance was putting her on a leash at all times. When she would. Show ANY behavior issues like this..we would correct her immediately and over and over again. She has to respect you both as her pack leaders. She needs to know she is at the back of the pack..behind your Shepard too.
Im also sorry for your loss..we lost a Dobie to our pool 20 years ago and it's still a painful memory.
