Our dog is a Shepherd/Collie mix She's about 5 yrs old. She started labor and had her first puppy just after midnight. She had her 6th puppy about an hour ago and I'm not sure she doesn't have 1 more yet. She's still panting a bit and periodically licking her back side as she would when she was waiting for the next puppy. It's almost 3:00 p.m. our time now and I was wondering if this was too long for her to be in labor? I don't recall any other dog I've had in labor that went this long. I know this dog had puppies before because she was still producing milk when found (she was a stray and was never able to be reunited with previous owners). So it looks like she was able to completely deliver that litter. All that being said, is this a normal length of time for her to be in labor?
