My cocker spaniel, Millie is 2 years old. We had her when she was 5 months old. For the first 6 months or so she was fine when taking her for a walk, she's always been a bit shy of other dogs and wasn't fussed about going up to them. But for the last year whenever were out and she sees another dog or person she just barks at them constantly. She won't go up to them, but if a dog starts to come towards her she runs away from it squeeling! She gets walked everyday so it's not like she's not used to seeing other dogs. Does anyone have any tips on how to get her to feel more comfortable around other dogs and stop barking and everyone and everything she sees?
