Teenager help – what is normal?

Our beautiful little Cockalier Poo puppy just turned 9 months old, and seems to have entered the teenager phase. She was quite a difficult puppy but with consistency we managed to nail her training and she finally started to settle into a good routine and her behaviour regulated.

However, the last two weeks it’s all gone out of the window. The main issue is, she’s ridiculously restless. It’s like she can’t regulate herself – she refuses to sit or lie down for a nap, and is constantly displaying anxious/bored behaviour: chewing everything in sight (doorframes, furniture, walls etc.), barking, nipping and pacing. She literally doesn’t sit still, it’s impossible to get anything done as she needs constant supervision. She’s crate trained so when things really get too much, we put her in there as a time out and she immediately falls asleep, but she just can’t seem to recognise when it’s time to settle down by herself – something she’d never previously had an issue with.

We walk her 30-60mins per day with plenty of time for sniffing and loose lead training, she has ~30mins per day of fetch/training outside in the garden and we have various mental enrichment toys like Kongs, puzzle feeders, yak cheese bones, snuffle mats etc. to ensure she’s challenged. I really don’t know what more we can do to enrich her – we both have full time jobs (working from home) and previously she’d just potter about by herself when we were on calls, but now she cannot be left for even a minute without causing trouble.

I know doodles are intelligent dogs and need stimulation, but taking care of her right now is honestly like a full time job, it’s relentless and we’re supposedly doing everything right. We ignore bad behaviour and redirect with chews, toys etc. and we reward good behaviour. Can anyone give me hope that this is just the teenager phase, or do these dogs genuinely have to be tended to every single minute of the day? I’m worried we’re encouraging/embedding behaviours – everything online suggests you should ignore attention seeking behaviour, but she’s destroying the house I can’t just ignore her! Any advice would help massively!
