In adult dogs, the total number of incisors is 12.

• A. False, the total is 6
• B. True
• C. False, the total is 8
• D. False, the total is 14

Answer: (B)

The main idea here is how many incisors a typical adult dog has. There are 3 incisors on each side of the upper jaw and 3 incisors on each side of the lower jaw. That means 6 incisors in the upper jaw and 6 in the lower jaw, for a total of 12 incisors. This matches the standard permanent-teeth arrangement dogs have (I 3/3: three incisors per side on both the top and bottom).

Options with counts like 6, 8, or 14 would not fit the usual adult canine dentition, which is why the statement with 12 is correct.
