How can I introduce our staffordshire bull terrier puppy to our eight year old Jack russell?

Of course it will get worse if you do nothing. Seek professional help for yourself on how to train a dog properly, before it injures someone, you're sued and the innocent dog is euthanized. Ignoring it is not correcting it.

Correct with a firm NO, then walk away. "and teach her it s wrong" Pray tell how do you teach her? Ensure active adult supervision at all times.

Do Not Leave Children Unsupervised In Or Around Any Dog(s). Keep them within arms/reach at all times. Children have been bitten that weren't taught how to behave properly around dogs.

No dog will put up with any unintended abuse from a toddler/child no matter how well behaved/socialized the dog maybe.

What did you think you were getting. A toothless chi? It sounds like you are clueless about puppies period.

Can you afforf to feed it Vet bill spayin? Hefty ins. Feed if it.

Bites anyone? Oh that's right can't get thst Money if it kills anyone? Willing to do prison time?

Or how about reading on how to raise yourpuppie and train it?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
