does any one have any Jack russell advice

we just got this awesome jack russell everyone allllways says they are so wild, not mine he goes thru some spaz stage then he is calm again he loves me I'm the moommmy I guess he will llisten to me better then anyone but I just want some info on training, and any other stuff, and is anyone else scared of little kids like 2 or 3 year olds??

I'm new to JRT's myself, having only had mine since February. Plus mine's only a mix, but being mixed with a Beagle, the Jack trait dominate him. Cute though, I'm the mommy too and mine prefers me more then anyone, he makes that VERY clear to the rest of the household.

I have noticed that Junior is afraid of being hit. This could be a result of his past as mine was a shelter dog, but sometimes he gets scared. His bold attitude won't allow a lot of submissive behavior though so he tries hard to fight it. It's sad to see him jump back and crouch to the floor if I accidentally hit him with the broom while sweeping, or raise my hand quickly while he's sitting on my lap. He is awesome with my son. My son is ten though and is very well aware of what dogs are capable of.

DId you adopt your dog from a shelter?

Be firm, with your JRT, but patient. They are stubborn dogs and will try to dominate you right off the bat. Be the alpha. It's difficult at first, but after a while he will see that you're the boss. Ignore him until you are ready to give him attention. When he comes to you for attention ignore him. At least through the learning period. Ever watch a pack of wolves on TV? If you can, pay attention to how the alpha treats the rest of the pack. You want to mimmick those behaviors.
