too protective and snapping at me!

Question
Hello,

I have a 5 year old boxer who is becoming very protective of our house. We have 1 acre invisible fencing so he's free to roam and I think he's taken on the watchdog role. It has gotten worse since we got our other dog, a pug,  2 years ago. Now, when I try to pull my boxer back from the window or balcony (after a firm NO), he snaps at me.
Also, to give you some background on Finn, I've been to 2 seperate trainers who have said that they've never seen a more dominant dog before. The first night we got him, he urinated on our bed. It's almost as if that he doesn't get his own way, he turns bad. Apart from that, he can be so lovely...just stubborn. I have taught him to sit/stay/roll over but only seems to work if alone and focused on him. If visitors are over, he acts like a toddler trying to get away with naughty behaviour while the parents are busy entertaining. It's been a long road and we are getting so tired of it. We are going to yet another trainer tomorrow who specializes in larger, dominant breeds. I'm worried that is turning aggressive and will bite me or one of my kids...
Thank you and would really appreciate your thoughts.

Hello Mellissa,

Please provide me with some more history so I can access Finn's behavior.

When did you get Finn? As a puppy or rescued? And, if rescued, do you know his history?

How was his behavior before getting the Pug two years ago? Non-aggressive and good, or had the aggressiveness begin before adding the Pug to the family?

Any changes prior? A move to this house and acre? A family member move out or in? Diet change? Routine change; job change, hour change, etc.?

Let me know and I will see what it possibly is. Trainers don't always access these questions and facts in order to train, and training isn't always the answer. Training is for younger dogs and puppies; modifying behavior is what you need.

As with Cesaer Millan the "Dog Whisperer" states, behavior modification is what dogs need, and training begins as a puppy so behavior modification is not needed.

Finn is 5 years old now, and training is not always possible. You cannot "train" behavior let alone, bad behavior. You modify it.
