I can’t believe that I came across your question, but I think that I’m trying to find the same game. For some reason the name Gus pops up in my head when I try and think of the game, but I haven’t been able to find it anywhere on the internet. I’ll let you know if I find it, and please let me know if you do.

its called dogamania! i got one at a garage sale and played it too!! its really wierd though, isn’t it? i dont have it anymore though.

Dogz or Dogs
i played a similar game but it was called Catz, my friend said their was a dog version though
