Absolutely, Raine was bought as a 'lab x' with the owners thinking she'd be a nice, easy-going family dog. They didn't know what a belgian shepherd is and just disregarded that part thinking that the 3/4 lab part would be the dominant side.
Unfortunately as you've described, the complete opposite happened - she's a nervy, very sensitive, high drive, very hard work malinois in a rather lab-ish body!
Same with River actually - 50/50 lab/collie, looks like it too but in her head, she is every bit a collie and although it wasn't why she was rehomed to me, it did cause problems with her original owners.
> A pup like you describe with a lot of work may come around a little, but you will always have an uphill battle and the pup will not be as mentally resilient and adaptable, and you will have years of having to work with this disadvantaged dog.
If it's done right this is not necessarily the case - but it must be done right. Opi was a VERY nervous puppy to start with, nervous dam and much like this pup very quiet and still when I went to see her (yes, I should have walked away but I was very green back then!). For four weeks she would not come out from under her chair in puppy socialisation class and was nervous of strange people and very nervous of children.
I took her to a second round of puppy class and through the puppy training course too, worked very hard at socialising her to everything and everyone, and by 6 months out she was very confident - kids took maybe another year to really get her confident with but unfortunately one stupid child did chase her trying to force her to say hello (needless to say that child got an earful from me, she was old enough to understand at about 8). But since then she has always been my most confident dog and remains so at 9yrs old, she has been a brilliant stooge dog for 4 years too and is still the matriarch of my little group.
It must be said though, I did know what I was doing when I was raising her - if someone is not 100% savvy with how to work a pup like her or this sprollie then they should walk away. It's not a job to take on lightly and I know of several dogs like this taken on by people who were not savvy enough to do it, who as adults all have big socialisation issues still and will have for some time (if not for life).
