In dire need of help.
We just got our first GSP about 4 weeks ago. She is 15 weeks old and in the last week has become really aggressive towards other people and other dogs. I had her outside with me while I took the trash out and a couple walked by pushing a stroller, our pup took off after them, hair raised on back and going after their feet, I got there just in time. Later that day we took her for a walk away from our house to see if that helped. She lunged and barked at every human and dog that passed us. We have 3 kids of our own who are 1,3, and 4 and all though she hasn't been aggressive towards them so far, I am worried about her being around them if she's getting this aggressive. Please someone give me advice, we love her so much and want to fix this before it gets worse. I dont know where else to go for help. Thanks in advance.
