[FIXED] [CD] (Smart) Dog will not go potty unless directed

Product: The Sims 4
Platform:Mac
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What expansions, game packs, and stuff packs do you have installed? All except Toddler Stuff
Steps: How can we find the bug ourselves? Wait for a dog to "go potty" on their own, without being directed
What happens when the bug occurs? I have an adult Irish Setter with Active (default for breed), Friendly, and Smart traits, who was added to an existing family as a puppy in CAS. She's been an adult for at least a Sim week, and she will still not "Go Potty" on her own. She never goes when taken for a walk either. She whines in misery until one of my Sims directs her to go. (When clicking "What's Wrong?" it's always potty; she is well-fed and played with frequently.) It seems that this problem might be tied to the "Smart" trait, ironically, as other players have reported it on the forums here: http://forums.thesims.com/en_US/discussion/929148/do-adult-dogs-ever/p1
What do you expect to see? Dog should eventually learn to "go potty" on their own, as the "What's Wrong?" pop-up says they should.
Have you installed any customization with the game, e.g. Custom Content or Mods? Never used.
Did this issue appear after a specific patch or change you made to your system? No

Adult dog won't learn to "go potty" on their own. Reported by a number of players on the forums: http://forums.thesims.com/en_US/discussion/929148/do-adult-dogs-ever/p1

ETA: I installed doggy doors when my dog was still a puppy, and she lets herself out to run around, she just won't "go potty" unless specifically directed.
