Thanks for your query,
Since you are not sure that it is not a bite,so i suggest you to get your child vaccinated.because rabies
is a fatal in nature,
First dose should be taken immediately preferably in 72 hours.
Schedule is day 0,3,7,14,28.
Give first 2 doses and keep an eye over dog for 10days,if dog develops any features of rabies full schedule is to be followed and if dog is healthy third dose to be taken on day 21 so as to convert it into pre exposure prophylaxis.
Wishing your child good health.
