i need to know the weight of adult sproker pls

As it is a crossbreed I would imagine it could be as low as Cocker and as heavy as a Springer.

Cocker breed standards says:  Size Height approximately: dogs: 39-41 cms (151/2-16 ins); bitches: 38-39 cms (15-151/2 ins). Weight approximately: 13-14.5 kgs (28-32 lbs) and Springer: No weight range given  but size Size: Approximate height: 51 cms (20 ins).  The ones I know seem to be about 35 - 40 pounds

That is assuming the parents were typical of their breed.
