dog to dog behavior
my miniature schnauzer does not behave well when passing other dogs. he will twist and/or pulls on the lead. if we try to stop to speak to the other dog, he is usually not happy to speak to them and becomes aggressive or if a dog is behind him, he will continually look behind instead of keeping his eyes forward in the direction he is going. he is 4 years old I have had him for only 5 months now. any ideas?
