Experience shows that the Y-harnesses flooding the market tend to place more strain on a dog’s neck than chest harnesses or Powerharnesses. In addition to incorrect sizing and adjustment, this is also due to the inherent Y-shaped design of the harness. They should be avoided, especially for dogs with breathing difficulties.
In such cases, a Powerharness can be a good choice, or an Y-harness equipped with the Duo-Flex system, whose flexibility provides maximum support for free breathing.
