We adopted three kittens. When we interrupted the nursing, Lucy would become very upset and quickly gather them together again to feed. Lucy will push him away but many times she will oblige. This is a hormone foul-up that's actually a variation of normal physical events in some female dogs. These confused girls aren't truly in a family way, but some will nurture and feed the nearest baby.
Milk production is common.
As long as Barney continues to use Lucy as his personal cafeteria, she will serve him hot meals. Eventually her milk production will taper off. Dr. Jeff Nichol practices at the Adobe Animal Medical Center.
