Molars have different counts between the upper and lower jaws.

• A. Incisors have different counts in the upper and lower jaws.
• B. Canines have different counts in the upper and lower jaws.
• C. Premolars have different counts in the upper and lower jaws.
• D. Molars have different counts between the upper and lower jaws.

Answer: (C)

In dogs, the number of teeth can differ between the upper and lower jaws for certain tooth types. Specifically, premolars are counted the same in both arches, with 4 premolars per side for a total of 8 premolars in each jaw. Molars, on the other hand, differ: there are 2 molars per side in the upper jaw but 3 molars per side in the lower jaw, giving more molars in the lower jaw overall. So the pattern that molars have different counts between the upper and lower jaws is the correct concept to understand.
