Or DDog3 as she is more commonly known 
In short, she's about 2.5, staffieXwhippet (most likely) rescued at 16 weeks where we were her fourth home. Little socialisation, no bite inhibition but a generally sunny disposition who fitted in immediately with DDogs1&2, DCat and DS(12)
I'm very experienced with rescue dogs, and felt confident that she would soon be the epitome of those placid staffies and whippets that I see everywhere 
Anyway, she's not.....
When we enter the house she's jumping up to head height, hugs are out of the question as she turns into a delighted, squirming heap then starts to jump again, she licks all the fecking time
On the plus side, she has amazing recall, is quick to learn when the mood takes her and is clean and calm in the house when she's not being interacted with, so I'm reasonably happy that it's not a food issue. We've recently started agility which she loves, though we have to temper any excitement or lavish praise, otherwise it sends her skyward.
The main problem is she's so affectionate and really seems to crave human interaction, but is totally unable to deal with it calmly so a vicious circle continues.
FWIW, out the house she is always on high alert and seems to panic if she loses one or other of us. We've recently had glimmers of hope for the future but I think it would be really beneficial for her (and us!) if she could just calm down a little in the meantime
