No. The Keeshond's thick coat sheds abundantly and, as a result, leaves pet dander in your home. Pet dander is the cause of most pet related allergies.
Keeshonden can adjust to warm climates. Their undercoats will thin out in hot and humid seasons and their coats provide some cooling insulation in the heat. However, their fur is so dense they are at risk of overheating in direct sunlight and when exercising in hot weather. Be sure to watch your Keeshond closely for signs of heat exhaustion and offer them plenty of cool water on walks and in the yard when it's hot.
Keeshonden can learn to swim and many enjoy jumping in the water or wading in the shallow end to cool off when it's hot. However, their thick coats can weigh them down, so Keeshonden should be watched closely when they swim, and their time in the water should be kept brief so they don't tire out.
