A fox and a pig and something else are investigating something. The game is from 1990-95. Around there. In the end they find some human ruins. Its isometric in parts, 2d in others. This is DRIVING ME NUTS!!! sorry to post here, but if anyone can help with this its adventure games enthusiasts.
That's Inherit the Earth, Quest for the Orb!
Edit: And the third party member was a deer!
