My 2 year and 4 month old GSD mated May 7, 9, and 11 so is ending week 7 today.
She didn't go through morning sickness. She did become ravenous a week post mating which lasted until week 5. Then she became a big pickier.
Palpation detected no pups but we did that at day 33, somewhat late in the palpation window so the vet said then that she could still be pregnant.
Size-wise, there is a bit of growth in terms of I don't see her ribs anymore. But nothing drastic.
I know normally bitches increase in size around week 6 onwards.
But is there a chance that she's still pregnant?
We mated her the heat before this but didn't conceive, so I was left with unused aspirator, whelp box, rectal digital thermometer, and other supplies LOL.
