Yes, wellies are generally good for dog walking, especially in wet or muddy conditions. They provide waterproof protection, keeping your feet dry and comfortable as you walk various terrains. Additionally, wellies often offer good grip and support, which can be beneficial during longer walks or when navigating slippery surfaces. However, it's essential to ensure that the wellies you choose are comfortable and provide adequate support for your feet, as prolonged use of poorly fitting footwear can lead to discomfort or even injury. You may wish to consider a wellington boot with a Vibram sole unit for better traction.
