A list of pets that dont smell?

All animals smell if not cleaned regularly. Fish are the easiest. Birds if you clean their cage at least once a week if you have an oversized cage. Cats are next but you need to clean the litter tray and if they go outside may become smelly if they come in contact with something smelly. Dogs are either way. long haired dogs tend to be the worse for the fact of the long coat. Short hairs are best. But regular baths are required or if you get a dog like a boxer or staffy and give them a regular water pond that is clean they will bath themselves during summer and hot days.
