that brings me on to the other annoying habit. Give her a biscuit she wonders around the house trying to bury it, whimpering. Then when she finds somewhere... Usually my settee cushions, she buries it down the side of the settee cushion or under it and then barks until I come over to retrieve it. She does this 3 times and then eats it... Messily.Quite often, if it's not an irritant issue, dogs lick their feet due to boredom or anxiety, as it releases endorphins for them. You may find you can 'cure' it by giving the dog some challenge to distract and entertain it - maybe hide a few treats around the room and let them sniff them out.
It's like a ritual. Or maybe she's autistic and needs routine LOL. I would imagine if I hid something, she'd find it and then call me to get it LOL she's such a diva
