Wow, it almost sounds like your dogs "knew" something. But on the other hand, maybe it was a poisoned animal & they knew to stay clear. Our Bassett Hound once found a skeleton near the river bank, in a place no dog could have gotten to without a lot of trouble. It was dog-size but we couldn't tell what it was. For remains to be skeletal, wouldn't they have had to be there a long time? How long has Isaiah been gone now? I truly hope you will see him again, or if not, that he is at least not suffering any more. C J
