My dog Mila (Daschund) is pregnant and should be 59 days pregnant (possibly more but very unsure). Her stomachs been hard since last night and she stopped eating yesterday afternoon but recently just ate again but only a little. She’s been a little strange today and yesterday but besides that she seems normal. She did lose her mucus plug Monday morning and a little more of it Tuesday. Could she be close to labor or possibly already starting first stage?
