Ghana can only be 350 or 2008 (clue 1).
2008 cannot be 315 (your grid), so Ghana cannot be 315 either.
Now 315 can only be Russia or Ukraine.
Neither byengo bat nor listner cat can be Russia or Ukraine, so 315 cannot be either of those animals.
The only animal left for 315 then is the dobra dingo.
Finally, since now dobra dingo and 315 must occupy the same row, then they must be in the second row.
This is yet another case of one of those "Of A and B, one is C and the other is D" clues that concealed the key exclusion very well. There are several additional Xs that can be gleaned from that clue.
Hope that worked.
