Going to put this on review for now but it would be great to get more info.
Hi crinrict, so I did some tests before the newest update. You don't need to be companion for feel the love to appear, it's just ups the points received to 250, without being companion it's 150 points. My child sim has just over half friendship bar with the dog, good friends status in the profile panel, isn't it's companion and could feel the love when it was in its happy state. It took quite a few interactions for it appear though, play, pet and give treat or giving her the wellness treat from the vets seemed to put in a happy state quicker. My other child sim has just under quarter bar friendship and I couldn't get it to appear for them at all they're also not companions. Molly does has the Loyal trait but I'm not sure if that has any bearing on it appearing, I don't have any other pets to test 🤔
