Our 6 month old working cocker spaniel is really settling in, enjoying walks off the lead, rooting around the garden, and snoozing on the sofa. She pulls on the lead, which I believe is quite common for the breed, but we're working on loose lead walking and it is getting better on quiet streets. The issue is that she's scared of traffic noise and so gets really anxious when we need to walk near traffic. I've been trying to build up her tolerance slowly with treats, praise and distraction, but don't seem to be making much progress. Is this something that will improve as she gets older and more confident, or is there more I should be doing now to make sure she feels confident?
