HELP: Linear mixed models

#1
In my analysis I am trying to predict how ratings of cuteness of dogs (5 dogs) predict the levels of depression for each subject.
Depression ~ Cuteness ratings
Now for each subject, there are 5 ratings (Cuteness), but only one depression score. Can I run this analysis with the single depression score for each subject?Thanks!
The data would look something like this ddd.png

Less is more. Stay pure. Stay poor.

Well, perhaps we need to think about the ordering of events. Can looking at cute dogs make you depressed or is it that being depressed influences your score. Especially since you are saying it is fixed.

Thanks. I suppose it would be the second, being depressed has an effect on how you rate the dogs. Would it work if I defined it like this?
(Cuteness ~ Depression + (1|subject) + (1|dog)?
