Part 2:
However, our lad is starting to show signs of aggression. It happens when we stop him from doing something, when we try to take something away from him, or when we "scold" him. He barks really loudly and stands up on his hind legs, leaning against us. He only weighs about 8 and a half pounds, but it's still very intimidating!
It mostly happens with my husband. Or with people who try to use a firm, loud voice to show authority—at least, that’s how it seems to me (though I might have misread the situation).
The reason I’m so devastated is that today he actually bit my husband and drew blood on his hand. I had pushed Loulou away because he was trying to jump onto my lap, and some coffee got spilt. My husband picked him up with one hand while I wiped it up. Our old girl (our Labrador) wanted to get past, so my husband nudged her away with one hand, and that’s when Loulou bit him really hard... Was he trying to protect our other dog, or was it out of jealousy?
I honestly don’t know, but we’re both in shock. Out of surprise, anger, and pain, my husband put Loulou down, but he tried to bite him again, so my husband shoved him away quite hard with his foot.
Loulou had "nipped" before, but never a proper bite like this.
I’m completely lost. Ever since we got him, I’ve read page after page of dog training advice. I’ve seen every possible opinion and its opposite. Some say Loulou is being "dominant," even with us, while others say dominance doesn't exist between different species.
What have we done wrong? Have we let things get out of hand? (He’s such an endearing, affectionate, and funny little dog that we probably let him get away with far too much...)
How should we react to a situation like this? Should we punish him? If so, how?
How can we make sure this doesn’t happen again?
We’re considering asking the trainer to come back.
Should we be looking for a "firmer" trainer?
I feel so helpless against our 8.5lb Loulou, which sounds ridiculous. We’re probably making loads of mistakes, but I just can't understand what would cause him to bite like that.
Thanks for reading to the end, and thank you in advance for your advice 🙏
