Honestly my girl is 10 months old and she DID grow out of biting, me nor my boyfriend have ever spanked nor used a shock collar on her and she has turned out great listens to basically anything we tell her...when she was biting we had and still do about 20 toys in the house she still plays and BITES thos but not anything shes not supposed to. I would NEVER hit a 5lb dog let alone use a shock collar on them thats awful!
