The canine then became overstimulated by this reaction and began to jump on and bite some of the children," Animal Care & Control says.
Animal Care & Control said six of the students received Level 3 bites.
The seventh student received a Level 1 bite, defined as "Obnoxious or aggressive behavior but no skin-contact by teeth."
Animal Care & Control says they made contact with the owner, who was visiting someone in Charlotte when the incident occurred.
Animal Care & Control says the owner left school property before they arrived.
