No offense to dog lovers, but I really hate dogs. Though, it's probably from my severe allergy to them.
At any rate, my first (and only, thus far) family to adopt a dog made over 200,000 from him in two weeks. Which was pretty awesome. In that time he collected 5 tiberium and at least 3 gigantic rocks along with various other gems and metals. So coming from someone completely and totally biassed against dogs, I can attest to the fact that they make much better money-makers than cats, and I think I've been turned to the darkside when it comes to dogs for sims. They're my new go-to pet.
I was really glad to see the results that you posted about using a sim to help them optimize their profits. I found that quite helpful and instructive, as aside from the tiberium I was simply selling all their gems and metals raw.
I apologize if this was already asked or mentioned, but in that 100 hours do you know how many special objects the dog was able to construct?
