I have had females act that way before. Some do get morning sickness too. How much does your female weigh? I think some of them get pretty uncomfortable when the puppies start growing and stretching their bellies. Low calcium levels can also cause that behavior. I don't believe in supplementing with calcium during pregnancies but there are a few rare exceptions where the female can get pre-eclampsia and calcium is necessary. Small females and females carrying large litters are most at risk. You might want to give her a little nutri-cal when she is having these shivering spells. If they continue you might want to ask your vet about them. |
