On the one hand I love this
On the other hand I now have a small fluffy white dog and am no longer emotionally sturdy enough to imagine such creatures in peril
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.
