My 5 year old lab is suddenly staying in her crate (open door) and shaking. She won’t come out and is acting strange. She is laying on a teddy bear. She has all shots and usually wet hyper and active. No signs of illness. What can we do.

Poor Macey! It could be something has scared her, or it could be that she is feeling unwell. This sudden change in behavior can be the first sign of illness, and the shaking could be due to pain or fever. I see that she isn't spayed. In dogs who aren't spayed, there is a risk of developing an infection of the uterus called a pyometra. This is very serious and fatal without treatment. One sign of it is pain. Because I can't see her in person to rule out a pyometra, taking her into a vet asap for a health check to be safe would be ideal. Otherwise, keep watch on her. If she stops eating, starts vomiting, becomes lethargic, her belly appears to bloat, she continues to act strange, and/or you notice a discharge from her genital area, get her into a vet immediately. The treatment for a pyometra includes spaying the dog. Best of luck, I hope this helps!
