Final answer:
Ruminants such as cows, sheep, and goats have a dental pad instead of upper incisors and canines, helping them digest fiber-rich diets.
Step-by-step explanation:
The animals that have a dental pad in place of upper incisors and canines are ruminants. Ruminants such as cows, sheep, and goats are mainly herbivores that have evolved unique digestive systems to digest large amounts of fiber. An interesting feature of these animals is that they do not have upper incisor teeth. Instead, they have a dental pad which helps them to efficiently tear and chew plant materials. Out of the options provided, dogs (carnivores), cats (carnivores), horses (herbivores), and rabbits (lagomorphs) do not have a dental pad in place of upper incisors and canines.
