She just started doing this about 20 minutes ago. Today she hasn't been too good at being with the puppies and I've had to lock her in there a few times. She's shaking and panting and heaving and her heart is beating really fast. I can't get her to the vet until the morning and I just don't know what to do. She ate some turkey earlier but I just tried to give some to her and she refused it. I'm freaking out and I have no idea what to do. Does it sound that serious? And by the way she had the puppies a week ago (November 20). Could it have to do with the daddy dog going in there some and her getting stressed? I just locked him out of there so maybe she'll stop stressing. Sorry if my thoughts aren't collected well right now but I have no clue what to do.. thanks in advance.
