Willow is now 5 months old, and just in the past 3 or 4 weeks she has become aggressive while eating. she has always ate extremely fast inhaling her food, like she is starving. I have increased the amount per serving as she has got older. 3 or 4 weeks ago while setting her bowl down she hit the bowl and some of the food spilled out, so as i picked it up to put it in her bowl she actually growled at me, i was in shock she has never done this before, since then my wife,daughter and i have tried to seperate her from her food many times and she does the same thing. what can i do to stop this behavior. the last two days I have been feeding her by hand a little at a time and she is fine,but eats it out of my hand like a vaccum.
thanks in advance for any advice
