Rosemarie, I'm so glad to see you back on EBN, we have missed you... and congrats on the baby girl. We really need to see some pics!!!
Your story absolutely breaks my heart, we went thru a somewhat similar experience w/Walter not too long ago. He was very aggressive w/my husband, and occasionally me... we hired a professional dog trainer in Nashville to help us out. She gave us a checklist of things to do, and thankfully having him neutered made a world of difference for us.
Please do NOT beat yourself over re-homing Brutus... I LOVE my dogs, make NO mistake about it... they are like my children. BUT my skin family comes first... if my dogs attacked someone in this house they would have to go. You have two little kids in your home... they are your FIRST priority, and you being the wonderful mom that you are already know this. I can only imagine how difficult this will be for you, but I would do the same in your position.
Sending you lots of hugs and prayers... please don't be a stranger, we are here for you and the family!!!
