No. Samoyeds shed heavily and, as a result, release pet dander into your home. Dander is the cause of most pet-related allergies.
Despite their luxurious coats, Samoyeds can live comfortably in hot climates as long as you keep them in air conditioning during the hottest part of the day. It sometimes gets hot in the arctic in the summertime, so their coats are adapted for the heat. In warm weather, Sammies will fully shed their undercoats so they don't get too hot. Additionally, the way the coat stands away from a Samoyed's body creates insulation that keeps her warm in winter and cool in summer. If it's very hot or humid, take your Sammy out only in the early morning or evening when it's cooler, and watch her for signs of overexertion or heat exhaustion.
Some Samoyeds may learn to like the water, but they aren't a breed that will jump into the nearest body of water to enjoy a swim. Their thick coats can make them feel weighed down when wet.
