So, its been brought to my attention that dogs in-game can be quite slow while traveling near/in shallow water, the "fix" was to allow your dog to swim across the lake itself but that is also quite slow to wait for.
This is a problem, especially when it comes to rivers. As they tend to be quite shallow near the edge in most maps and any water that is ankles-deep, is enough to make your dog do the "shake water off" animation over and over again, until they are completely out of the water, which is very annoying on maps like Te Awaroa.
Solution: put a cool-down on the animation.
