Increasing Happiness

Hey there guys.
I have a problem over days. I adoptet a horse from the rescuecenter with 0% happiness. I cared him every day, but more than 25% is not possible. What can i do?

How long have you had it? it may take a while for it to increase since it naturally decreases a bit everyday. try to treat with bagged/crates/bunches of treats.

Happiness for horses will increase gradually as you care for them. Each daily care action will raise happiness by 5% and a treat will increase happiness by 15%, so at the end of the day your horse should be able to get to 30% happiness at least if you do everything.

Each new day a horse loses happiness by 10%, which will eat up two care actions worth of Happiness leaving your horse progressing very slowly if you don't get any treats to boost happiness.
