They are covered by enamel which protects it from decay but get broken.

Animals do not eat as much sugars and carbohydrates as humans and due to their life expectancy being a lot lower than humans, they do not outlive their teeth.

They do decay, at least some of them, but seldom at the magnitude human do.  For some of the animal they have tooth that grow continuously throughout their lives like in rodents and lagomorphs (rabbits and hares).  For canines the teeth are less likely than humans to form dental cavities because of the very high pH of dog saliva, which prevents enamel from demineralizing.  And some other animal like reptiles and shark, their teeth are replaced throughout during their life.
