The Canid is an alien race that resembles the dog species. They hail from Canidon.
A Canid wears a space suit when on Earth. It has a picture of a dog bone in a red circle, with a pattern of yellow lines surrounding it on a grey background. The helmet covers their dog-like heads. They wear red gloves, boots and underwear.
The Canid managed to successfully take over the world in "They Hail From Canidon". Johnathan Gabriel thought it was a dream and told Tycho Brahe about it, who revealed that it had actually happened. They told Tycho to fetch a frisbee.
They were probably defeated in the end and sent back to Canidon where they belonged.
