Biting Jack Russell

Question
We have a 2 year old JR, Indy, who has become increasingly aggressive as he has gotten
older.
His aggression is territorial in nature and always involves food, crate, any kind of meaty
bone (which we stopped giving him a long time ago!) or his bed.

He has bitten all of us including my 10 year old who needed stitches and just recently bit
my 10 month old baby as he crawled by his food when he was eating.

We all love Indy very much.  We have tried, obedience, personal trainers, profiling, talking
to his vet who breeds JRs.  We have put his bed upstairs, worked with him while he eats,
exercised him every day until he drops and nothing seems to be helping him.

I have never had a JR and I accept full responsibility for being the possible cause of his
aggressive behavior.  Perhaps there is something we should have been doing differently
but here we are now.  
We have been at this "cross roads" with Indy before, but when I saw my little babys
bleeding hand I knew that as much as I love Indy, some thing must be done.

I don't want to put him down, but I will if that is the best thing.  Rescues wont take him
with his history of biting and giving him away could put someone else in danger.

Sorry this is so longwinded...thank you and I look forward to hearing what you have to
say.

Hi Lorien,
I'm sorry you're going through this, and to tell you quite honestly, it looks like you've tried everything you possibly could. I certainly wouldn't say you were giving up easily. Biting anyone, but especially defenseless babies is absolutely intolerable.
I am a jack breeder, and I love the breed more than any other but there is no way on earth I would put up with my dog biting my baby. What if it was the baby's face and not the hand???
You really have tried everything that I was going to suggest. Indy is not a good choice to have in a home with children. Maybe he is high strung and would do better in a household with older people in a more quiet atmosphere.
I would try a few more rescue organizations one more time. Have you reached out to the JRTCA? They might be able to put you in touch with an organization near your home. They have a page on their website that has rescue sites that may be able to help.
Here is the page:

Lastly, try not to feel bad about having to place him somewhere else, you really did give it your all, and there is no one that could blame you for choosing your own baby over a dog. Yes, we love our dogs A LOT but not at the expense of our children.
Sometimes the two are just not a good match.
Wish I could have helped a little more but maybe you just needed some reassurance that you are doing the right thing.
All the best to you and your family.
If you ever do decide to get another dog... or a JACK, go for the shorties (not the Parsons) they are family oriented, lovable, docile, and great pets.
Take care
