That all depends on the apparel you are looking for. Many solutions in the raingear line are either waterproof or water-resistant, as are some select Canada Pooch coats.
The hot pavements boots aren’t waterproof, but they do have holes that are designed to help water drain out and keep their feet cool and breezy. The Wellies, however, are designed for rainy weather, so they are waterproof to keep out the wet.
Items like the cooling vests are actually designed to retain water—this is to help achieve the cooling effect. When you add water, it helps lower their body temperature.
If you’re curious about whether or not the item you are considering is waterproof, make sure to read the description of the product or the tag if you’re in-store.
