Dam is JRT with three day old pups. She and the pups are in a completely seperate room from other dogs. However, when she wishes to come out for a brief walk, or to go outside, I let her.
With her pups safely in there bed, and behind a closed door, she has lashed out unprevoked at one of our dogs twice now. The first lunge at him was blocked by my right arm, and I sustained a painful "nip." The second occasion (same other dog, still unprovoked) was blocked by my left arm; and, this time I have a substantial puncture wound on the base of my hand.
Is this maternal aggression? The pups are safe in a completely different room when she does this. This dog she is lashing out at, for no apparent reason, was her best play buddy up until two days prior to whelping.
Any advice please? Obviously, I've taken to keeping him out of her way when she needs out of the room for a bit. But, should I expect this new hatred of hers to last, or to subside eventually?
