Loki sounded like ONE HECK OF A DOG. I find it so amazing what dogs can do for us and you know sometimes I do not think we give them enough credit. I will share a story with you that is very touching at least to me anyway LOL. I had a siberian husky named Blade I got him for my 5th aniversary as a present from my hubby. He was an AWFUL puppy LOL, but turned out to be a wonderful freind. I have always been a dog trainer and always tried to offer service dog training to people that needed it at no cost to them, I wanted to show how a SNOW DOG could make a great helper. He learned all the tasks very quickly but we mostly were doing threapy work and one day at the nursing home I worked in I had him with me. Blade got very excited over a particular woman not typical of him, well he would not leave her alone he kept tugging at her sleeve and I was trying to stop him, well he tugged until he got her to sit on the floor, sure enough with in seconds she had a seizure he layed there by her and was barking or should I say WOO WOOING Sibes don't really bark LOL, untill someone other than me came. It shocked me I would have never guessed he could have done that. Blade unfortunatly died in 2004 because of his love for people someone felt the need to show him not all People are kind. I will not go into detail. I miss him very much.
