I got another slayer task using dogs, but the only dog locations I know of are the mansion in ardy and mcgregor's woods. Anyone got any idea of where I can use a cannon on dogs?

There's a bunch of dogs in the Karamja dungeon, but I don't know if that's one of the zones where a cannon is not allowed (since I've never really used one).

 

 

 

Might be worth a shot since there's a location where there's about 7-8 dog spawns and nothing else.

Brimhaven dungeaon. There is a room that has lke 5-7 spawns. I don't think it is a good place to cannon, though. I just melee them straight up.
