my long hair miniature dachshund is expecting she is 6weeks along this Sunday she will be 7 weeks along. My question is it normal to feel them this early? Could it mean she is having a large litter? This is not my first litter my other female had 2 litters I couldn't feel them until the end of the 7th week. She has a vet appointment in a week to do x-rays I'm just really impatient sorry
