I have said this before but as someone with a lot of experience working with dogs in vets and shelters. I just feel I have to mention it again so you can get a different opinion. Be very careful with the dominance structure. Val Bonney's book was written at least 10 years ago and a lot of opinions have changed since then.
It is now more important to think about the associations your dog has with your child to prevent bites. Regardless of pack structure (which was used to explain every behaviour problem several years ago) if your dog has negative associations with your child then he is more likely to bite your child. If your dog has positive associations then he is less likely to. I strongly recommend talking to a dog trainer accredited by the delta society, or a vet behaviourist rather than learning from old books. The RSPCA up here (QLD) does training and behaviour problems and their trainers are all accredited through Delta. Their methods are up to date and based on learning theory and research.

Ultimately you will choose your own way but I do feel responsible if I don't put my opinion forward on this. Good luck.
