This year it falls on a Sunday, as it is only a 'commemoration' it is not celebrated or transferred. (I dont know what strings the BBC had to pull to have Dibley's Blessing of the Animals on a Sunday.)
So for those who want to remember Saint Francis on the 4th of October, I have included a collect and a prayer blessing below:
Collect for St Francis of Assisi:
A Saint Francis Day Prayer:
Loving Father, Saint Francis taught us to love all of your creatures and to care for those we have charge of, we thank you for N. ( & N.), for the companionship we share and the support we offer each other. Help us to understand and promote that bond of affection we have with our animals and to share our love with each other. Through Jesus Christ our Lord, Amen.
