I got her 2 years after i got her son from my uncle, very high prey drive and reactive to small adult dogs, she has killed multiple rabbits and one 14 yr old pug but it was right after she had puppies.  She will chase loud noises semis, garbage trucks sometimes( we have worked on that for the last 5 mo. She is pretty good but once in awhile she will try if i dont catch her before she fully engages. She also reacts agressivly to dogs who are in distress with her son like if i steped on his toe and he yelped she would come over and beat him up.
