That’s bullshit. Those little dogs can be made to growl at anything. My wife’s dog would rip my arm off if I reach towards her and say Mama. He makes that little pipsqueek in the video look like Bambi. That dog has no comprehension of the size difference he has been trained in guarding his food and that is what he is doing. The guy opens the box and his hand threatens to take the tiny burger eliciting a response that looks like what he is describing but it is bait for a “viral” video. I clicked to watch it and he got a plus from it and whoever posted it here is compicit in a lie
Clearly a setup for the video clip.
