The Classic is Springland's middle-of-the-range bottle, and for most medium dogs, it's the natural go-to. Squeeze the bottle with one hand to fill the attached bowl, then release to let any leftover water drain straight back inside, simple, mess-free hydration wherever your walk takes you. The leak-tight shut-off keeps everything contained when it's not in use, whether that's in a bag, a backpack, or the car.
At 22oz, it's a solid match for dogs around the size of a Golden Retriever, Pitbull, or Australian Shepherd, bigger than the Mini, without the bulk of the largest size in the range. If your dog is especially thirsty, or you're heading out for a longer day, it's worth sizing up to the Large. Made from food-safe, BPA-free plastic, it fits neatly into most standard car cup holders and comes with an included carabiner for clipping straight onto a bag, backpack, or lead.
