Sorry about your beloved dog.
I can appreciate Finn's pragmatic approach to firearms and hunting. Unfortunately or fortunately? I am a looney. I have played with and hunted many cartridges and rifle combinations. I do not for one second wish, I had not done that.
The right rifle can certainly make any cartridge stand out. The posted article speaks of two such rifles that were chambered in 308. I have owned a couple 308's, but the platforms never grabbed me. Maybe a "scout" rifle should be in my future.......
The 308, like the 30-06 and a few other cartridges are never a wrong choice.
