So me and my girlfriend rescued a dog on Friday. We introduced our beagle first before we brought Addie home and they got along fine the first day, even sleeping in the bed together. Since the first night Addie has snapped at our beagle and lunged towards her. I don't want it to escalate more than that, I understand she's probably stressed and it seems like she gets jealous when we show our beagle alot of attention. But how do I keep her from snapping and lunging?
