I love Marilyn, and I have been in rescue for over 10 year, and in AKC dog clubs / shows just as long - she has helped with so many of our dog, I could write a book. I first met her while training one of my labradors for AKC shows - and I told her about a Great Pyrenees ""rescue failure"" that was not fitting into my home pack of 3 large dogs and being aggressive. She worked with all of the dogs, and with me to become the ""Pack Leader"" and by the end of the 4 sessions, there were no more 'surprise attacks"", no more dog fights, NOTHING - everyone was happier and communicating - I was amazed! I have since called her for every rescue that is fearful and destructive or not bonding in the pack welland showing aggression - and have recommended her routinely with others that have fearful or aggressive dogs - and she has always had rave reviews! ;) Yes, she uses the submissive hold technique - but that was the key for us in bringing the ""dominant"" behavior under control (& my Pyr is over 100lbs) - it didn't hurt him or scare him at all. For another dog, she didn't do that all - as his needs were different. If you have tried everyone else without success, don't give up - try Marilyn - she never gives up on you or your dog.
