Hello PodSquad,
Sorry for disappearing for a couple of days. @Starmerdramallama's comment hit me between the eyes and I was having serious doubts the day I got back because he was just being horrible, horrible, horrible.
However, I've had two and a half (and counting) days of lovely behaviour from my Pod, I think attributable to having two mornings in a row of important work calls Wednesday and Thursday, so I put him in his crate with a Kong and went upstairs to do my calls, he had 90 mins sleep both mornings, and it seems to make him much nicer to be around. So I did it again today, and again he slept for 90 mins without waking. And now he's in the garden chomping on his bone.
On the strength of trialling leaving Pod alone for a few short periods of time, me and DP left him for a whole 90 mins in his crate with a Kong Wednesday night and went to the spa for a much much needed sauna and hot tub (I kept checking the camera so I could nip home if he became distressed, it's only 5 mins away) and it was absolutely blissful to recharge together and see our friend and yet again he slept the whole time.
It's still stressful and hard and tiring and I get monched when he's over-excited but I keep glimpsing these little miracles happening between us. My favourite is this: when Pod has had his afternoon sleep, which he usually does beside me or laying on my legs, he goes into this 'not awake but not asleep' mode where he rolls around on his back, having tummy rubs and making little ruwl-ruwl-ruwl noises and licking my arms and its just SO lovely. That alone is helping to counteract the niggling worry that rears his head when he's being a dick, which is "he's feral, he'll never want to live in a house with people, he hates it here etc." When he's sleepy and calm he's so affectionate with us.
Also, next week trainer is taking us to his vets (another local one) for a second opinion to rule out whether Pod has any underlying pain that could be causing his up and down behaviour, and then he said he'll give us things to work on from there.
