Aggressive Australian Shepherd Pup
We just got a beautiful 15 week old male on the 19th. The first few days of settling in were great and he's such a joy to hide Beal and play with.
The problem is now it's that he's starting to show signs like he's aggressive. He's come up behind my two year old twice now grabbing her hair up while snarling and once went after her face as she sat on the floor playing.
Haven't drawn blood but she's starting to call him puppy mad and is getting a little afraid of him.
He also launched himself at my 14 year old son for simply walking over and picking up a pair of shoes before my pup could get to them.
Is this actual aggression or am I getting worried over something that could be fixed with some training? Need some advice so I can make this home happy and safe for both my pup and my kids.
