Mom was bitten by Weet!

Remember Weet, my sisters Shitzu dog. She bitten mom last Wednesday!!!! My goodness I am so afraid that time. Here's what happened,Mom was on our living room, I think she was reading. And then she heard Weet barking real hard. And then mom went to him and she saw Greta our Labrador trying to bite little Weet. Mom hurriedly got Weet and I pushed Greta away. And all of a sudden mom was bitten by Weet. Maybe she taught mom was hurting her. Poor mom she was trying to save Weet and then she was the one being hurt. I also saw Weet's dog supplies are scattered on our garage because Greta was playing with it and destroying it. Poor Weet! I am sure my sister will be very angry with Greta now.
