9 week old Aggressive blue heeler Aussie mix puppy
I bought a blue heeler Aussie mix puppy and have had her for a week and a half. We had to put my year old border collie down from a rare case of diabetes, who was our world and an amazing calm and smart dog. So we got Josi to help with the loss of Hoss. Josi our new puppy is starting to lunge at my face . And she is biting extremely hard. She's growling and I really feel its not just a play growl. She came from a good breeder and she's 9 weeks. I have tried
Yelping when she bites too hard for nearly 3 days and it didn't do a thing.
If I spank her she lunges at my face barks and will go to the other side of the room and lay Down and completely ignore me like she is very mad.
I've tried saying firmly NO and ignoring for 10-20 seconds.
I've tried these each for about 3 days straight. And have been Extremely consistent. She gets great exercise and is on a good diet.
What else can I try. Help please!!!!
