Ushi No Tane Forum

Just got myself a pet, and with it some questions came along:

1. Is it safe to take it "out" of its house when its raining or should I just ignore it on raining days. I tried interacting but it got a red angry mark as soon as I took it for a walk in the rain.
2. Why won't it fetch the bone? I got a dashchund with the herding/healing trait, I take it for a walk and throw the bone and it doesn't fetch. Tried doing it in my farmland and in the cities and it still won't fetch.
3. Does taking the pet for a walk award additional friendship points or just talking everyday is enough?
4. What does the healing trait does?

The only one i can help with us throwing the bone when your on a walk to throw it you need to be close enough that the animal shows up with an a button like when your picking it up.
