Hi, I'd love some recommendations for a harness that will suit the frame of a fully grown Flatcoat (2 1/2 yr old). My previous dog had a broad, flat chest and we had two styles of harness that fitted him comfortably. My Flatcoat has more of a pigeon chest and neither sit well on her, 'cutting' into her chest or putting pressure on her skeleton around her neck and chest. A 'Y' shape would be best so as not to restrict movement of her front limbs, with a good attachment point between her shoulders I should imagine. She pulls like mad on the lead and until I can do some training on this matter, a good harness will put less strain on her and less damage to her throat. Thanks.
