Extremely valid! An optional rule is provided for making dogs immune to harm, but a lot of the content here expects they can sometimes be in danger.
If you're looking for rpgs where the dogs are not in danger, I have one called Guardian (https://kumada1.itch.io/guardian).
Also Jeeyon Shim's Have I Been Good (https://jeeyonshim.itch.io/have-i-been-good) is really excellent.
