Hi there and thank you for your question. I am a licensed veterinarian and would be happy to assist you. It sounds like the medications help, but you are not wanting to medicate her daily. What I really recommend for these cases is a DAP collar. It stands for Dog-Appeasing Pheromone, and the collar releases a pheromone that mimics the pheromone released by the mother while the pups are nursing, so it can soothe dogs. It has worked for similar situations with many of my patients. You can purchase them at online pet stores or local pet stores:
Hope this helps! Best of luck.
Thank you so much. I will give this a try.
