Thank you all for your replies. I have taken her to obedience school so she does have training. She has never once aggressively went after the lab, it's only the puppy. For instance, on Friday morning I was sitting on the ground and the puppy came to me so I was petting her and then the basenji came running up and aggressively biting the puppy. I tried to block her from biting but she bit my hand and then she took a chunk out of my forearm. The scary thing was, she wouldn't stop.

Most of the "attacks" (not sure how to word it otherwise) are random. Sometimes the puppy will just be walking away and Marley will go into her aggressive mode and jump on her and start biting the puppy's neck. The puppy will be screaming and it's difficult to stop Marley from biting unless we physically pull her off. This happens about 10 times per day. The ones that I have seen, the puppy has not been provoking Marley.

Hello to all-

We have a 2 year old female basenji, 8 year old lab and now a new 3 month great dane. Our basenji, Marley, has been extremely diffcult as of late and I am in need of some advice. She has always been aggressive towards dogs except for our lab. When i take her on walks, she pulls very hard to get to other dogs and I cannot distract her. Since she was a puppy, she has been around other dogs and I thought that she was well socialized. Now, I think not. She has become extremely aggressive with the new puppy and me! She's attacked the puppy almost everyday and attacked me as well when i was petting the puppy. Also, everyday since the new one arrived, she has pooped twice each day in the house! I am at my wit's end especially since she attacked me. Any advice would be much appreciated, I don't know what else to do.

thank you so much!!!
