Pablo update: Having issues with being left on his own

Ruth contacted me a little while ago as she was having issues with getting Pablo to settle when left on his own. I rung her and had a chat and put her in contact with Lisa, who has Tucker, who has uses an Animal Behaviourist and has had a  similar issue with Tucker.  Pablo is from Ernest and Blottie's litter of ten puppies again. He is a half brother to Tucker, as they share the same Mum Blottie.

"Thank you Jane, for calling me and for passing my email to Lisa. It was really great to chat to you, you’ve given me some really helpful advice.
Here’s an up to date picture of Pablo for you and a video of him jumping for joy at finding a stick. He really is so lovely. 
Many thanks again,
Ruth"

This bit of video (below) that Ruth sent me, does make me smile.

So a couple weeks went past and I emailed Ruth to find out how things are going.

"Hello Jane, thanks for your email. I hope you’re well.
We got a Behaviourist in and she thinks instead of isolation anxiety, Pablo gets anxious being confined and is hyper-attached to me. So we’ve ditched the crate and the pen for the time being, and Pablo now sleeps in the playroom. The first night he protested a lot, less on the second night, and from the third night he did not bark at all and just fell asleep. I am back in my own bed and we are all happier getting a lot more sleep. 
I started from scratch with leaving him alone during the day, building up slowly from 30 seconds so he doesn’t get stressed, and he can now do 4.5 minutes. I’m also doing very slow crate-training in the day so he is still used to it but not stressed by it, in case he absolutely needs to be in the crate in future (at the vets or to recuperate at all).
Pablo and I met up with Lisa and Tucker on Friday, it was great to meet them and get some advice from her. Pablo and Tucker enjoyed a nice long muddy walk in the park and they got on well. I’ve attached a picture of them, tired out while we enjoyed a coffee after the walk. I was surprised to see that at 7 months Pablo is already bigger than Tucker, I think Pablo takes after the Brittany slightly more than the Cavalier.
Thanks for checking in on us, it was great to talk to you a couple of weeks ago and you really helped me get the ball rolling with making improvements to our situation.
Hope you’re well and enjoying a slight break after most of Rosie’s puppies have left for their new homes.
All the best,
Ruth x"

Pablo and Tucker

"Hello Ruth,
Really good to hear that things are going the right way again and that you have met up with Lisa and Tucker. Tucker, although the same Mum, has a pure Cavalier Dad Casper. So he is 3/4 Cavalier unlike Pablo who has only 5/8 Cavalier. Tucker has two litter siblings Eddie and Alfie who dwarf him. Tucker was one of the smaller pups in the litter when he left us. 
In the photo with Tucker, Pablo's expression is very much like his pure Cavalier Grandmother Smudge, but with more length to cranium and muzzle. She was always a gentle, happy dog. 
Thanks for updating me
Jane x"
