The best place to get him would be at Valguarde in Howling Fjord. When I was farming for a Rare I had a level 25 as backup and two level 20-22. I fought each spawn and by the time I had won the battle another spawn had popped up. Just kept going until I got it. Also, cycling through my lower level pets helped to get a few level ups too!
Best time to get him is defintely after a server reset. The first week I had all the spawns to myself and only saw two Uncommons and no Rares. Second week there were a few other campers and on my third fight I got a Rare. Lucky! Good luck to others!
