My pup got spayed yesterdqy and since I brought her home when she is sleeping or resting she gets these kind of like shivers, only on bottom half of her, it seems to be when she breathes in each time. Hard to explain what it is, Is that normal?

I don't really know. You might want to check with the vet. They may want you to bring her in so they can observe the shiver if possible.

I read online that they sometimes get tremors from the meds, maybe that is it? She whines a bit, she sleeps in the crate next to me and she whined at 2:00am so I got up and took her to the puppy pad and she peed some. She is still out of it, only wants to be on my lap, hard to get comfortable. Good thing I took the next 2 days off work. I hope she will be back to herself soon. That dang cone gets in the way of everything, doors, furniture, etc. 10 days with that thing on doesn't seem like it will too much fun.

My dog just got her stitches out yesterday and never wore the cone. I refuse- she licked a few times but never chewed or pulled. I had 2 other dogs fixed and never let them wear the cone - ya just tell them to leave it or whatever term you use. Hopefully some type of training has happened now to help.

I was thinking maybe she is in pain? Did they give pain meds? My dog was so out of it the first night but by the next day was fine. I hope they did not over do her. Will hope for the best

Sometimes shaking happens after a dog is spayed. Try covering her with a blanket, she might be feeling cold.
