As with most sighthounds our whippet’s neck is wider than her head so using a conventional sighthound collar doesn’t work - she can back out of it easily as we found when we went to collect her from the rescue rep. Since then we’ve used a harness. I started her with a Ruffwear harness which is very secure but somewhat bulky. I then tried a Dexil which is slightly lighter but comfortably padded. Both the Ruffwear and the Dexil harnesses are secure. However for warmer weather (I’m a born optimist - albeit disappointed most days) I tried her today in a lighter Doodlebone harness. Unfortunately when I wanted to go forward and she didn’t share my interest the harness was pulled off. Fortunately she allowed me to ‘reharness’ her, something she wouldn’t have done 12 months ago - she would have legged it. Does any sighthound owner use a light but secure harness which they would recommend? Something similar to the Dexil but lighter.
