When we stayed at Wij-land another boat moored next to us. The couple on that boat were accompanied by a dog, too. A six months young Vizsla (https://en.wikipedia.org/wiki/Vizsla) to be precise, called Vita. The dogs liked one another at first sight. Although this perhaps looks mean, it’s pure play/joy. Btw ours, the hairy one, is an Australian Shepherd - https://en.wikipedia.org/wiki/Australian_Shepherd.
