My cross breed Alsatian/rott gave birth to just one rott
But this was her first crosssin

Lol.
Of course it's normal. Like you said, it is her first cross-in.
You have nothing to worry about.

its not usual but its certainly not abnormal

This is serious, how many times did she achieve successful locking with the stud?

that vet must be a quack to ve initiated that routine,what was his goal ? something of that nature is not done considering the fact rotts nd GSDs 're not of same specie ,some sort of interference must have gone wrong during the gestation period. next time select a particular breed for crossing throughout ur bitch ovulation period.
