Take a look at the sentence again:
Miguel bursted out laughing when he saw
that Rey, his ferocious Chihuahua, had bitten
the seat of Julio's jeans and hung on as
Julio danced around the kitchen, trying to shake off the little dog.
The first verb, bursted, is incorrect. You cannot add an ed to the end of the simple past. The chart below shows the correct forms.
| Verb | Simple Present | Simple Past | Past Participle |
| burst | burst(s) | burst | burst |
Had bitten, the verb you chose, is perfectly correct. Before you continue, review the rules for irregular verbs.
