Why is my dog whining when lying down or turning around? Is he hurt?

This sounds like your pet is painful somewhere. Typically musculoskeletal (muscle or bone) pain will cause whining during motion. I would recommend feeling around on your pets body for any particularly painful areas (if you wish to investigate first). If there are painful areas, then take this concern to your vet so that they can do a good exam of the area and make the best recommendations moving forward with your pets care. Typically for muscle sprains they can be treated with just NSAIDs (non-steroidal anti-inflammatorys) with good success. However if the pain is more internal and possibly a bone or ligament the vet will most likely recommend x-rays to evaluate the areas of interest further.

I am sorry Luna is not acting right and thanks for using pet coach. It is possible that Luna has strained a ligament or even soft tissue. I would recommend restricting her activity for two weeks. This includes being on a leash when outside and no running/jumping. However at anytime if she is getting worse or not improving I would recommend taking her to a vet for a good exam. I hope that helps

Your dog needs veterinary care immediately. He could have a problem with the vertebrae in his back, a fracture or tendon injury to a leg, or severe abdominal pain. A full exam by a vet will help to zero in on the site of the problem, and then appropriate treatment can be given.

IF he is whining this is an indication he is in pain but there are many possible injuries, infections or accidents which could cause it. A full check up and possibly xrays is recommended if it persists beyond 12hours and your vet can prescribe appropriate pain relief and treatment once the cause has been identified. Keep him well rested and on a deep, soft bed in the meantime

If your dog is an older dog, it could be that she is suffering from arthritis and it's painful when she lays down. I would her seen by a vet in the next couple of days for this problem. It could be that she would benefit from some pain medications, which the vet can prescribe.

Caddy looks really uncomfortable in the photos. It sounds like there is a source of pain, judging from the photos, thid could be pain in the abdomen or in the back or legs. It may also be something simple like full anal glands. I would give him an hour or so to see if he settles in case its just a gassy tummy, but if he doesnt I would take him in for an examination.

It does sound like your dog could be in pain, and that could be causing the restlessness at night. He simply can't find a position that he is comfortable in, and it hurts to curl up. He could have an injury to his neck, spine, hips, or limbs. I would take him into the vet today for an exam. He may also benefit from pain medications if he is in pain. Do not give him any human pain medications, many are toxic to dogs and fatal if given. The vet can prescribe him safe pain medications if needed.
