Totally agree with the advice Varga has given. I will also throw in, as someone that has a child and cats/dog, that there IS a very important second level of training that must go on with the child/ren. Varga said it very politely. I, and I don't direct this at YOU, specifically, but in general, stress the heck out of child training.

All children must be taught, at an early, early age, and IMO, disciplined as least as equally as the pet, if not more so, what the proper handling/playing 'rules' are with pets. Children must be taught what the warning signs are, what tail positions mean, what the lowering of the head means, etc. J is 7, and I can't tell you the number of times he has cautioned another child about this child's pet, "Hey, don't you see....., leave her alone".

All dogs bite, it is just a matter of when. I believe this, and I teach this to J. It isn't much different than the stove, the street, or around a pool of water. *Most* of the time, these are 'safe' areas, but as a matter of routine course: don't touch the stove, don't enter the street, and don't go near a body of water.

Kids should be viewed by animals as the giver of yummy treats. Kids should be taught to feed a dog, but never approach a food bowl otherwise. Dog toys belong to the dog, and kid's toys belong to the kids, and never the two should meet.
