We get month by month too due to weight check too - though last time vet gave me 2 months supply as she was unlikely to go past to the next weight bracket in that time.
YamyamPup has hit adolescence bang on 6 months. She's really changed, I thought it was the dodgy tummy but now thats all cleared up it seems she's just growing up!
She's become a lots more whiny/vocal. A little 'jumpier' in terms of loud noises etc.
And the chewing and constant scavenging has gone up to a new level, I didn't know was possible!
She's also suddenly gone off her crate. She would normally take herself off to her crate every evening and tuck herself on for the night but the last 2 nights I've had to 'help' her into it... and then she's woken up at 12 or 1am and not been able to resettle after letting out for very quick boring garden trip.
Exhausted!
Last night I popped my t shirt in which seemed to help, and today i'm going to work on positive association again, feeding meals in there again etc. Plus washing all her bedding.
Any other tips? And anyone else experienced a sleep regression??
