I bought this for my labrador when she was a puppy. The nappy is very thick and very water-absorbing. I ordered a second time when her first period is coming (10 months). The ads picture showed a golden retriever so I thought my labrador could fit it. I measured her stomach for 64cm. But when I put on the nappy, it is quite small for her. It is so tight that she couldn't even sit down properly. The picture is quite misguided and I don't think this product is suitable for large breed. And the measurement of the stomach should be less than 60cm at least if you want your dog wear it comfortably.
