My little girl had her second heat and her and my little boy tied 6 times that I saw/caught them. I personally think she is pregnant; she's very grumpy, she's getting a little fatter (she's at most 35 days pregnant), and her nipples are still very big. If she is pregnant, she'll be due between Christmas and New Years. I was just wondering a couple things: What necessities I'll need if she is pregnant (i.e. whelping supplies- obviously a whelping box, heating pad for the puppies), and when the vet can tell if there are puppies. I know some experienced vets can palpate the puppies, but I've her different time frames for x-rays. Any help would be appreciated!
