Looks like you ladies (ojanpera & Nikki) may need to get prepared for a litter of pups. Some of the signs are there but it can be unconfirmed for up to 5-7 weeks along. Unless you take them in for an xray. Usually done around 6-7 weeks along to be sure how many pups she will be having. Which I think for you first timers may be a really good idea. But than doesn't leave you much time to prepare. It only take 9 weeks for pups to be born.
When was the tie ?
Any weight gain?
Any sign of a milk line? (bumpy area that start on either side, starting at the vulva and running up along the nippy's)
If you think that you girls are pregnant start reading up on care of the dam, whelping and care of the pups afterwards. Be sure to make time for thier first visit for dew claws and tails to be docked. Oh and put back some money for emergency c-cecton.
Keep us updated on their progress and get ready ! Ask questions and lots of them. If possible find a mentor (a breeder in your area to help) and who you can go to for a better idea of what to expect. You always hope for the best but need to be prepares for the worse. You never know when a pup or even your girls need more that you can offer them during a difficult whelp. Have your vet and emergency vets # on hand.
