I had a situation with a beautiful Chesie I had from rescue. Wonderful dog, bonded with me in an instant. Only 1 yr. old. He was great with all of the family with the exception of 1 (out of 10) grand daughter. From the instant the child walked into te house, he'd go for her. We tried, REALLY tried, but I simply could not risk injury to the child. Sadly, we had to return Charlie to rescue.
There is no easy solution, but as you know, all it takes is an instant for a child to sustain a life altering injury (emotional as well as physical). If there were no children involved, you would have a bit of time to work through the aggression, to see if you could change Bella.
This is my opinion only... I would not risk it, when my son was 2 a dog attacked him. It was the worst thing i could ever see even the thought of his scream still bring chills down my back. My mom called me as he was getting rushed to the hospital and all i could do was drive as fast as i could to the hospital while i was on the phone listening to him. He ended up with multiple stitches in his face. The dog belonged to a friend of my mom. The owners knew he was not good around kids and did not say anything to my mom when she took him to the friendís house. My son did nothing to the dog; he was sitting in front of the TV watching cartoons. The dog walked by and just turned. Both the owner and my mom agreed that my son never even so much as put a finger on the dog. If there was no children in the house i would say try to work on it, but you donít know if you was to leave the room or answer the phone that can take your eyes off them and thatís long enough. For something to happen. Im sure there is a right home for him/her but maybe its a home with adults or older children.
I don't know how far you are willing to go to rehab this dog. but thier is hope and this can be fixed. check out the dog phsycology center of los angels. do a googel search. there is a incredible dog trainer thier named ceasar millan who has rehabed many of these types of dog. and has beeen very successful. I have cured my dogs of some toy guarding and some fears using his techniques. i have to say very effective.
Its very sad to hear that you have to have your dog put to sleep. My mum had a Jack russell called Rikkie. He was out in his garden and one of my cousins started teasing him with the food bowl. Well the dog got pi**ed of and attached himself to the childs hand. We had to have Rikkie put to sleep as the family of my cousin Complained. That child was the devils spawn though and he would always come over and pull the cats tails, poke the dogs through the wire with sticks etc. In some ways i think it was the childs fault as he was a nasty little bugger and had it coming but my mum was always worried about whos gonna be next. So we burried him in the garden with daffodils on his grave. Its a huge shame that the corrective behaviour only worked for a short while. ~twinkletoes
I am so sorry about Bella. I know how much you love her. Wish there was a miracle somewhere for you and her. Its so sad to think where some of these dogs come from and what they have gone through to still have to pay the price for being mistreated. She probably could have been teased or whatever before you got her. She could have had such a good home with you, so sorry again.
