Accidents happen no matter how careful we are Kodaka. I, like you am super protective of my babies but one of them slipped down and broke his leg in January, went into cardiac arrest at the Animal Emergency Room and left me............if I just hadn't let him get up, if I had just caught him.......all those thoughts went thru my mind. One thing I do know tho, Ghost knew I loved him with all my heart. He was a 13 year old shepherd and had lived a good life. I now just thank God for letting me have him for 13 years and for sending him to me to begin with. Asya was blessed to have someone who loved her so much and she lived to a ripe old age. She loved you and would not want you to blame yourself I am sure and one day you will get to see her again. Just think of all those puppy kisses she will have saved up.
