MY dog killed my sweet angel, best friend cat. I found Sootie a couple of hours after it happened, it could not have been more than 3 hours at most that I seen him last. I am just sick about it, but I could deal with it better if i knew he died an immediate death and did not suffer. He was already stiff, when I found him. He had a large hole on hisright side, up near his armpit, about the size of a nickel and another smaller hole on the opposite side around the same location. The blood that was under him, it wasnt a whole lot, more so when I moved him, was maroon in color. His skin was all torn up, around the wounds, but I m hoping that occured after death. Do you think his heart was punctured? Is that a very quick death? Sootie was about a 10 lbd cat at most and my dog isa boxer shephard mix, to give you an idea of how he could bite my cat around the chest. Since everyone is concerned about what is being done with my dog, here it is. he is only alittle over 1, he was abused and we adopted him as a rescue. He has never shown any aggression towards humans or other dogs. He is very affectionate and loving.Yes, I have to overcome some resentment and feeling sick about it, but it does come down to, they are animals, and we can not hold them accountable as we would a human.They avt on instinct, alot of the time. I love all animals, and this is something I must learn to forgive but never forget. He will no longer be allowed to be upstairs around the children or cats. He has a brother dog, that he is very close to, a llarge lab. Together when inside they will stay in a 8 foot by 6 foot kennel, furnished with water, beds, and toys. We purchased a large 10 foot by 20 foot run for them outside. He will only be allowed free roam when me or my husband are outside watching him. I will also give him a long runner line to be when supervised.
