After using this Puppia soft harness on Raul, a Boston Terrier, for about a month I was extremely happy with it. It is made of a soft mesh material so it was gentle on his shoulders and looks very cute at the same time. I dressed him in a red one to match his coat but it comes in a wide variety of cool colors and patterns as well, making it more stylish than the average harness. It was also very easy to take on and off of him with an adjustable chest belt and quick-release buckle and he did not mind wearing it for long periods of time (so it must be comfortable)!If your dog is a puller this will certainly be gentler on their chest and shoulders than the average harness, but it does not offer any features to help train your dog to stop pulling. Also, if your pooch is a little Houdini when it comes to slipping out of harnesses this may not be as secure as you need, though with the average pooch this should not be a problem. I enjoyed using the Puppia harness on Raul and we got many compliments and people asking about it when he wore it. If you are looking for a soft, comfortable harness for you pup this may be the right choice for you.
