I inherited a rescue dog not too long ago and she had puppies on 7/21. She is showing food aggression toward them and I don't know how to ease the situation, to move along the weening process, which according to everything I've read starts at about 4 weeks and should be completed by 8.5 weeks. She is the first dog I have had that I didn't raise from a puppy and she hasn't proven to be quite the difficult young lady(roughly 3 years old) She came from somewhat of a chaotic environment. I do believe there was abuse involved. I've tried to stick with positive reinforcement, instead of yelling and the like, but I just feel like I've made no progress. She has been an extremely good mother otherwise. She's very attentive to her puppies and they're extremely healthy. I refuse to let her take chewing treats in her puppy room with her, due to her aggression and the only thing I've found effective is moving the food somewhere, where the puppies cannot reach it, when I'm unable to supervise them. Should I just start to put her outside for awhile and leave the food available to the pups so they could at least sniff it? Leaving her food aggression to deal with after they're weened? I'm at a loss.
