Beautiful & Sturdy

I love this martingale! It's well constructed and striking! The ring you attach the leash to is a little too heavy. My pup seems to shy from it when I go to put it on. I don't think he likes how heavy it feels between the heavy-duty hardware and the weight of the Fi unit itself. I really hope he gets used to it. I use a thick martingale when we go to obedience training and it wasn't working to ALSO be wearing his Fi collar. I bought this Fi compatible martingale so he would only need to wear one collar to training. When we get home, I switch back to the regular collar, so the Fi unit needs to be removed from his SeaFlower collar and put back on his Fi collar. It only takes a minute or two. I gets tons of complements on the pattern (blue smoke) too!
