Immortal/custom dogs: No Health Decrease

The title might seem odd, but I am suggesting that dogs who are immortal or a custom should NOT have their health decrease as they get older. They can't die due to low health to begin with correct? That's the point of being immortal, being able to stand the test of time and live forever.


The problem I have is that as I look through my list of dogs on my kennel, all the older ones are my custom's and in the morning their health is near the 20-30-ish which scares me. Since their immortal though they shouldn't die to begin with? I then have to waste bathtubs and brush's to make their health go up again and I'm always worried that they might die. My idea is that Immortal or custom's don't have their health decrease, it will help me/Alacrtians focus on our older dogs who really need the bathtubs etc and extra care.

I know some people will say "let them have their health low, they can't die anyway" I still have to waste bathtubs and etc on them when I want to breed them or do anything with them really. (That's my other point)
