Puppy teenage regression

Hi!

We have had our rescue Irish Doodle (poodle x Irish setter) since 3 months old.

He’s now nearly 8 months & he is really in the thick of his teenage craziness.

Do we have a serious issue, or are these all common issues that he will work through with consistency from us?

1. Sudden intense lead pulling – constantly pulling on lead, knows to come to heel if we stop- but goes straight to pulling

2. Ignoring us when outside! No treat is good enough anymore, outside is way too exciting and overwhelming (even short ‘boring’ walks)

3. Demand barking – will occasionally start demand barking, whether it’s to play or just for attention

4. A new one this evening – toilet training regression! He has been perfect with going outside to toilet since about 4/5 months, no accidents inside, consistently signals- however this evening he has peed twice inside with no signal!! Fully emptied his bladder.

I’m constantly stressed that he’s going to be a naughty dog. He learns so quickly but we’re really struggling with these elements and seems like nothing we do will click.

Any reassurance / advice would help so much.
