WOW, I've just finished reading this entire thread ... twice. What a mess! What's happened here?
Jag posted a HOLY CRAP this is what just happened ... and most people SLAM her to the ground.
Why do you let him dictate what transpires in the house? He's not even a year old yet. If it were me, I'd not let him do that type thing. He must respect you and realize that you're not being harmed.
I think if you're in control then you need to be the judge of what's "okay" to "protect" and what isn't.
When your dog makes it's own decisions on that, that's a problem.
I do not see your puppy's behavior as protection but rather resource guarding/attempting to control, neither of which are behaviors you'd want to encourage.
That's essentially what I've been saying.
Whether it's actual "brave" guarding or resource guarding, it must be stopped.
You need to take control of this puppy, stop him from making such decisions and take over making decisions for him.
As I mentioned, it'll extend to humans soon enough this way. Not good at all. When I see people bragging about how their puppy guards...it's always a red flag, sorry.
I'm speaking from past failures on this one. The moment he came running towards you, you should have corrected him. When he grabbed her, you should have corrected him. He should never have had the chance to stand in front of you to block.
This behavior can tip the scales between the two dogs. Once it has, it's very difficult (and in my case, I've failed horribly) to fix.
I allowed something very much the same take place within my current dogs. Admittedly, I watched with surprise when it happened. If I had reacted and continued to watch for the red flags and corrected, I would not have to crate and rotate for the life time of two of my dogs now.
The two dogs I refer to were best buds as well. Now, they can't even be in the same room together.
I think we have to remember that our dogs can read our body language as well as the body language of us humans better than we ever give them credit for. If your dog was growling(seriously) at you and you were reacting (fear) to that growl then I think I'd have given him a free pass for correcting the dog you were playing with. But it was obvious that you were playing - albeit rougher than normal - it was considered by both parties to be play.
The few people that spoke up, their posts were completely dismissed:
Puppies do like to surprise us, don't they
I actually love it when I learn something new about Spirit ... whether it's positive or negative. It's all just getting to know your dog and learning and growing together.
Jag will be prepared next time. I am sure this post was a "holy cow!" post, and not a " I don't know what to do" post.
Next time Grim does this, she will correct him.
What I am seeing is not an owner who is not in control, but an owner who is being constantly surprised by a puppy who is not expected to behave this way until much later.
THIS (as per Sunflowers and Jo Ellen) is exactly what I got from Jag's THREE posts (why she felt the need to repeat what happened three times is beyond me. Her first post was crystal clear).
It stuns me that so many of you would slam Jag so quickly.
Did she miss the boat on stopping Grim from "bullying / being alpha / whatever" towards the pug. Sure, she did! I'm sure she was more shocked / surprised than anything, and the 5 or 6 seconds it took her to recover were too late at that point to do much. TIMING is everything ... we all know that.
BUT does that mean she deserved what was thrown at her? Come on ... how many of us have missed the boat the first time? ALL of us ... Not ONE of is perfect and has instantly caught every single "infraction" our dogs have made. If we did we wouldn't have a sub-category of aggression on this forum.
Jag - I know you're moving today, and your life must be very hectic right now! Good luck on the move ... and looking forward to hearing more stories about Grim and his shenanigans.
