I live on a large property. My partner and I are retired and are very active hobby farmers. We are looking to get a puppy and there are Kelpie x Jack Russel available or Cattle dog x. We have a 9 month old granddaughter who visits regularly. I read some report that Kelpie and Jack Russel are not good breeds to have around children. Somewhere else I read that Cattle dogs are not good around children..... any advise from the experts?
