He is now close to 11 weeks.
I don't really do what he wants. But the pulling gets out of hand sometimes, to the point where his collar almost comes off (hurting himself too in the process, I don't want that to happen). And this happens altough he knows he gets something special outside. I usually take him in my arms and move around a bit, try to relax him, before going back inside.
When he gets annoyed because of the treat, I wait until he settles and try again. If he starts biting, I stop altogether. I try to combine things and it's usually no longer than 5 mins, give or take. I basically combine all the basic stuff (sit, lay, crate kibble hunt and some other things) with toy play, to break the repetitivness.
And by physical play, I mean basically playing with toys. Tug of war (I add Leave it everytime), fetch (kind of, he brings them back most of the time until he gets bored :)) ), passing toys around with my girlfriend so he gets a good run.
But yea, the most problematic thing is his frustration when taken to potty. As I said, I feel like he got a bit more distant since this started happening (2-3 daysa ago?), since he seems to get frustrated faster and it escalates faster too.
Question, would holding him close to my chest when he is over stimulated, to relax, a bad thing? Could he see it as a alpha roll? He seems to be fine, although he whines at first, but the second I let him go he's back at it.
PS: One thing I noticed earlier. We were chilling on the couch and he was chewing on a toy, when suddenly he came to me and started to bite my tshirt/pull/growl a bit. I figured I'd give potty a try and when straight to his spot and he pooped. Now I don't know if this was a coincidence, but I hope not, because I was excited. He doesn't say a thing when he needs to go, even if in crate. I just have to wake up before him or see him sniff/run around.
