My girl is PG and in her 57th day. Today she is acting weird. In and Out. Wanting under the porch , [she is not an outside girl], respirations up to 115, temp.99. She has spent a lot of time in her whelping box. But she also is pacing, pacing, pacing. Is not eating unless I feed it to her. People food that is. Absolutely no dog food. Is drinking some, and peeing. We have been on walks of a sort. The snow is up to her back. She still wants to go down to the pasture to feed all the other critters. But is not interacting with them. Just sits and waits for me to get done. What can I expect next?
