Hi guys! It's been a while since I've been around, but I had surgery and have some free time

I've been laying around for 3 months now, and my little girl has developed a bad habit. I have 5 pups (I think they are all alpha). Zoe (momma) and Robyn have stayed at my side; the boys just visit. Now, almost anything on the bed, Robyn will guard. She gets stiff and starts to shake and growl real quiet. Soon mom decides to see what she has and will take it. After a growly fight, I (hopefully) save the unfortunate item. She will also bring items, socks, stuffed animals, small plastic things.... Now she is guarding the comforter or pillows. I am spraying her butt with conditioner to see if she will stop. But I am afraid that Zoe will hurt her if she doesn't stop. We had a similar problem with Trina; and now she is living with my mother. (mom is secretly hoping to get robyn, too)
