Yes, West Highland Terriers, including white Westies, do shed. However, their shedding is relatively low compared to many other breeds, and they are considered to be a hypoallergenic breed. Westies have a double coat consisting of a soft undercoat and a coarse topcoat. They shed their undercoat twice a year, typically in the spring and fall, which can result in more shedding during those seasons. However, with regular grooming, including brushing and trimming, you can help minimize shedding and keep your Westie's coat looking healthy and shiny. While Westies are considered hypoallergenic, no dog is completely allergen-free. People with allergies may still have reactions to Westies, but they may be less severe than with other breeds. If you have allergies, it's essential to spend some time around Westies before adopting one to see if you have any allergic reactions.
