Do I need to train Chop in GTA5?

The iFruit app isn't really working for me for some reason, and I know some people don't have ios or an iphone or whatever so they can't do it anyway… But is it really important for me to train him? Like, can I still play the game without it?

Chop is pointless, he doesn't do much but sit in his kennel, you can play the game without him

Hmm. I thnk you should
