We are having a problem with our puppy Tulip. She is a WILD child and walking her on a leash is exhausting for me! With Peanut, our older Corgi, I used a martingale when he was a puppy and now he's a great walker. But Tulip isn't having it, the collar isn't effective on her. I was thinking of trying a Haltie or a Gentle Lead. Has anyone used them with their Corgi? Any other ideas, save for getting Cesar Millan involved... lol. Speaking of Cesar, I was so sad to hear that his pit bull Daddy passed away this past Friday. What a beautiful dog, and what a wonderful life he led. RIP Daddy.
