hi,thx for the good luck wishes the algerian herder was a great watchdog ,energetic agile and ,fast for a mastiff alert ,ready for action My dad and uncle used to have a an Algerian mastiff they practically grew up with those dogs, and they didn't tell me about any accident or aggressive behavior of one of this dogs toward children, the villagers lived so close to their animals in general and they don't tolerate any aggressivety against their family members , nobody does of cours ;) but i meant that it's a basic point on the selectif process what created this breed during centuries , very very loyal and faithful too , I remember a story told by a French officer, during the 19century ,a village in the gate of the Algerian desert called Zaatcha resisted to the French army, and after some battles it was practically erased ,the house was destroyed and the people killed or deported , what shocked the French officer is that after some time the dogs of this village what lost their owners started to attack the French brigades what was passing by the way of this village they didn't stop till that all of them was shouted
