Our black lab Hugo is about to turn 9 and has just undergone an operation due to a ruptured cruciate ligament. He also has some arthritis. We ordered the large bed and hoped it would provide him with a more comfortable space. HE LOVES IT! Top quality materials and design. You just know quality when you see and feel it. Nick was so accommodating of our request to try the bed for size - Hugo is a LARGE lab. We also purchased a leather collar - again the best we have seen. Thanks Nick and the team! PS I have a sneaking suspicion we will before long also buy the large mat for Hugo when we travel.
