To start with Cesar has his way with dogs BUT he has made an assessment using his YEARS of experience with handling MANY dogs…Please don't assess your dogs behavior yourself – better to seek a professional …look for a trainer with aggression experience (possibly someone who has trained police k9 and understands what can trigger aggression) and also look into a behaviorist (a vet with behavior specialty) you may also have your vet check his thyroid as a LOW THYROID or (Hypo-thyroid) can have aggression as a side effect along with nervousness .Medication along with behavior modification may also help …

Like others on here have said it is hard to assess a dog on the internet but from what you have said it sounds more like fear based aggression not a dominate issue — please don't try pinning the dog like Cesar does as this has been known to make aggression worse and if it is fear based you definitely will make it worse!!

I would also be careful allowing the 11month old with him — just because he isn't showing aggression with her doesn't mean he won't and when he /if he does it won't be pretty !!!!

And if you like watching dog training shows try watching "It's Me Or The Dog" with Victoria Stillwell on Animal Planet Fri nights — she is soo cool!!!!! and uses more positive training and has worked with aggressive behaviors on her show….Check http://www.animalplanet.com for times and listings in your area…

Cesar still works more with actual training which is command-response instead of having a clear understanding of the importance of a dog's emotional response in helping the dog become less fearful and aggressive by learning new, more acceptable coping behaviors. He tends to use "flooding" more than counter-conditioning or desensitization which are evidence-based, humane methods of behavior modification

Having said that, thanks to "Cesar," all kinds of behavioral problems seem to get chalked up to "dominance" issues, even when that has nothing to do with it.

I think there is a possibility that the real problem is "fear aggression" which is totally not the same thing as "dominance aggression." Fear aggression is common in scared dgos, and that might be what you are seeing here. The appearance might be the same unless you know the subtle signs to look for, which is whay I say to get a good behaviorist. The kicker is if you mistake one type of aggression for the other and use the wrong methods, you'll make things far worse than they were. A fear-aggressive dog needs positive reinforcement, a dominant-aggressive dog needs corrections. That is oversimplified, but gives you an idea of the need to have a reliable expert see it first hand.

Good luck.

Watch her ears, her itty bitty tail and her eyes, mostly, and you'll learn the difference between her 'talking' and her real warning of a growl.

if she is otherwise sweet and no seen prediction of a bite, then you should be ok. I'd just watch her around people. Too many people take this the wrong way and react in a way that they shouldn't.

EDIT: Cesar Milan is not all he's cracked up to be: http://www.4pawsu.com/dogpsychology.htm

His theories are about 10 years behind current thinking. Not only that, but his techniques are extremely dangerous for people who do not know how to use them properly.
