re: Dog just snapped at daughter

One thing we found to help resource guarding is “trading”. Again, this is no substitute for actual professional advice, but training the dog that letting you take something away from him will be rewarded can help. Find some badass treats that he really likes, something that he will like more than his stuffed animal or bone (cheese, liver treats, a better bone), and offer it up as a trade for what he has. There’s articles about this online. You should do it first, then let your wife, then work with the kid ( not all in one sitting though). You can also practice with food when he eats to keep him from getting aggressive around the bowl… put half his food down and when he finishes it, grab the bowl and put more food in it, so he sees it as a positive thing. Do the same with your wife and daughter.

You want him to be comfortable and not growl around food, toys, etc. but you also don’t want to pester him all the time, so be sure to teach everybody that he needs plenty of time left alone also. That way, he doesn’t feel like every time he gets something he likes, somebody’s going to mess with him.
