I would like an interaction that would be like "sneak (pets name) table/sim food" when eating a group meal with other sims at a table, especially for child sims. Also another interaction option when not at a table of "give (pets name) sim food" Those would both work well with glutton pets.

Also I agree with the option of making home made dog food. It would work well with cottage living because you can get fresh meat and fresh eggs from chickens and such, and also it would work well with the off the grid lot trait and being frugal for freegan sims who hate spending unnecessary money.

I am not sure about fresh pumpkin though. Fresh pumpkin from an actual pumpkin is likely to give dogs diarrhea so maybe there could also be a bad outcome reaction for all of those things that may vary a bit between individual pets to give pets more individuality and character like pet fears.

Also an interaction for werewolf sims that have the hunter perk to give some of the raw meat they get from hunts to pet dogs, and werewolf sims that have the group hunt perk and a pet dog with the hunter trait to go on a hunt together for raw meat.

Also for the fishing skill the option to give their pet cat or dog some of the raw fish they just caught.
