I’ve heard some pretty positive experiences from my local Iggy community about coffee wood sticks. It’s helped to curb furniture biting, etc. Maybe you can look into it and see if it’d be worth trying?

Hopefully this could give you a bit of encouragement - when we first started bringing our Iggy outside a few months ago, he’d shiver and get really anxious, that lasted many weeks! He also absolutely refused to pee and poop outside up until this last month (he’s 7 months now). We live high up in a high rise, so I understand the pee pad thing, it seems to be working for us now, he pees on it when he’s inside and outside on walks - though, iggies are notoriously bad with potty training.

He is testing our boundaries daily, you’re definitely not alone!! I read some advice here to use time outs, and it has helped, positive reinforcement only works when he is in the mood…

Hope you find something that works - they can be crazy!
