I've just got my second rescue greyhound. First was a delight from the word go, so when she died I wanted to rescue another. I've got a lovely girl, finished racing a year ago, and she's as different from the other as can be. She's very bad walking on the lead, as is frightened of so many things so I got a Halti harness for her, and because I'm an idiot I can't seem to fit it back now I want to take her out. Has anyone used one of these? Or are they totally unsuitable for greys? I'm just not happy with it, and I don't want her to lose what little confidence she has in me. Help, please!
