Boykin Spaniels are relatively adaptable to various climates, but care should be taken in extreme temperatures. In hot weather, they are prone to overheating due to their dense coat. It's essential to provide them with plenty of water, shade, and opportunities to cool down, avoiding vigorous exercise during the hottest parts of the day. Use of cooling vests or mats can also be beneficial. In cold weather, their coat provides some insulation, but they may need additional warmth such as sweaters or coats when temperatures drop significantly, especially since they may not have the thick undercoat that some winter breeds possess. Monitoring them for signs of discomfort in extreme temperatures ensures they stay healthy and safe throughout the year.
