Okay so my yorkie is due next sunday the 20th of July. Today she is on her 55th day and in her 8th week since her first breeding. I was giving her a treat and a touched her front paw and I heard and seen her growl she has never done this before. She has her milk slowly coming in and she also has a slight pant and to her that she has had for the last 3 or 4 days she also sleeps almost all day. Is the growling a sign of her close to labor? If anyone can answer this please help! She is also picky on her treats and sometimes the food.
