Hi all, might seem like a silly question but I have no idea what size harness to get for an 8 week old staffy pup! I have looked up average sizing for staffy puppies with no luck, it's all suggestions for adult dogs. I know each puppies size is individual but i'm really unsure on what sizing to go for. I was looking at getting a Julius-K9 harness for preference. any suggestions and advice would be greatly appreciated. Thank you.
