So I got this collar after my dog would slip out of the martingale with chain. To be fair, I had stopped using it as the martingale as I wanted to guide him and not subdue him.
With the chain martingale collar I found it affected his fur colour where the metal rubbed his fur.
With the web martingale, I am able to gently guide him or nudge him when he is not paying attention to our walk.
What I love with all Ruffwear web collars is their washability. I washed the old collar that had gotten rather dirty. It washed up super easy with dish soap and warm water and looked great!
The martingale with web and clip now just stays on the leash. I unclip the dog as we get back from our walk and the collar remains on the leash. He seems to be quite happy with it. And I find it stays on him very well (though I could have gotten a smaller size)
Over all, I wish I had gotten him this collar sooner.
