I have a 8 month old Female German Shepard puppy. I got her when she was 1 month old. Our beagle was there before her and is about 3yrs old. The GS has attacked the beagle about 3 times in different instance. 1 time she was out side and saw the beagle eating a piece of cereal that had fallen on the floor; she attacked him when she came in. Another time the beagle was barking at something and she attached him. This last time a piece of bread was given to each dog and the beagle was throw and thrashed around by the Shepard. My wife and daughter had to pull her off of the beagle in fear of the shepherd killing the beagle, the beagle was bleeding. 99% of the time the dogs get along and she tries to get him to play with her. Confused and worried about the Shepard's nature. Seems like she just snaps into an attack mode and attacks the beagle. She is very sweet to the whole family and we are all very attached to her. When the beagle is not around she looks for him and checks all of the rooms for him. I want to keep her, just don't want her to kill the beagle.
