That's great to hear.
My Renton tends to be mega-slow, rather than pull. He has to stop and sniff every single lamp post, doorway etc. It literally trebles the time it takes to get anywhere. Except when he sees a squirrel and bolts so fast he'd probably rip the arm clean off some folk. He's great off the lead on long walks though providing there are no dogs around with toys (he will steal them and bolt at 35mph) or folk having a picnic as he will steam in and eat anything. Had dogs when I was younger that were so clever and easy to train. Just think he's a sub-par hound, though very loveable.
