Arnold was a stray that was brought to a shelter . I saw a Facebook post with his picture and I picked him up the next day before he was put down. He has been excellent and is a really good example of how rescue dogs can be very solid dogs with the right leadership and training. Arnold has proven to be loving, intelligent ,loyal and solid nervesl. He has very good protective instincts and is more on the defensive side. Not very prey driven but during protection work he takes it very serious and has shown that he will protect me without hesitation. He is pretty social with other dogs and most people but on initial meetings he can be a little skeptical at times. All in all he is a great dog that can relax all day and protect me if he has to. I cant ask for much more than that.
