Sims are refusing to interact with pets

[KiilthCruelti]

Ok, so I just made a game in with my sims living in an apartment, 2 teens and a dog. I've been trying to
get the sims to interact with my dog but they just won't!
Plus, my dog has fleas now. Has anyone else had this problem, or at least have a way to fix it? =(

I'm guessing that you have at least one mod installed to be able to create a household with no adults.  If that's the case, it's possible the mod is messing with your game.  There are others who can help you with much better than I can.

Exactly what happens when you try to interact with the dog?  Do any options appear when you click on the dog?  If so, what happens when you click one of them?  As for the fleas, your dog will need to be given a bath in a bathtub or you can purchase a pet shampooer with pet Lifetime Happiness points.
