“Pet” and “petted” come from the same verb, but they are used differently because they refer to different verb forms.
Pet is the base form and can describe an action in the present or after helping verbs such as will, can, and should.
Petted is the past tense and past participle of pet in standard English. For example, “I pet my dog every morning” describes a regular action, while “I petted my dog yesterday” describes an action that happened in the past.
This difference can be confusing because English has many irregular verbs, while pet follows a regular pattern.
Understanding when to use pet, pets, petting, and petted makes your writing and speaking more natural.
if you are an English learner, student, or simply unsure about the correct form, the examples below will make the difference easy to remember.
Quick Answer
Pet is the base form of the verb, while petted is its past tense and past participle. Use pet for present or infinitive constructions: “I pet my cat” and “to pet a dog.” Use petted for completed past actions: “I petted my cat yesterday.” The -ed ending is pronounced as a separate syllable.
Why Do People Confuse “Pet” and “Petted”?
People often confuse these words because pet can function as both a noun and a verb.
As a noun, a pet is an animal kept and cared for by a person:
- “My cat is my favorite pet.”
As a verb, pet means to stroke or touch an animal gently:
- “I pet my cat every evening.”
The confusion usually appears when someone needs to describe the same action in the past:
- Present: “I pet the dog.”
- Past: “I petted the dog.”
The spelling also looks unusual because pet is a short, one-syllable word ending in a consonant. When -ed is added, the final consonant is doubled: pet → petted.
