Lulu is a brave pet in our shelter．

As you know, there are a lot of forest fires during the summer season．Many forests are badly 1 by fire each year．Not far from our shelter, a forest caught fire during this hot summer．We were in a heat wave which had been  2 for three days．

Lulu rushed towards the forest where flames sent out a terrible 3 ．I no longer had any hope that Lulu would come  4 to the shelter．In fact, I was waiting for the firemen to announce his 5 in the forest, when suddenly, a fireman burst into my shelter and  6  me that my dog Lulu had  7 to save four kittens who were trapped by the flames．According to the fireman, Lulu seized the kittens, one by one moving them to a  8 place．I immediately accompanied the fireman to the forest to  9 the rescued kittens．When we arrived at the  10 of the incident, we found Lulu was not  11 ．Then we heard the  12 of a dog came from the forest barking furiously．I  13 it was my dog Lulu．The fireman followed the tracks of the dog until we found him barking  14 by the side of an injured fireman who was lying on the ground and desperately 15 rescue．Thanks to Lulu, four kittens and a fireman were saved．
