hiya very sorry to hear about ur dog, i know what your going through as my dog in my avatar pic i sadly lost him back in May to a kick in the head from a horse, its not nice seeing it happening and having them dying when theyre in front of you, but he had a good life and at least hes not suffering no longer and is in the best place now. Its just one of them freak accidents that happen. I was full of anger when it happened to me with my dog and cried like a bloody baby knowing that i was gonna lose him but what can you do. In a way you cant be angry with the owner of the horse cause they werent
