My dog is walking with his head down. Is he in pain or injured?
It's very likely that this is a [painful condition](https://www.petcoach.co/article/5-most-painful-conditions-in-dogs), as evidenced by the fact that he doesn't want to hold his head up. It could be due to a sprained muscle, a pinched nerve, or something more serious involving the vertebrae in the neck.
Most of the time these situations do not resolve on their own, and I find that my patients need pain medications and potentially muscle relaxers, as well as strict cage rest for at least 2 weeks. In addition, you'll want your vet to do a thorough exam to rule out [Intervertebral Disc Disease](https://www.petcoach.co/dog/condition/intervertebral-disc-disease/) (IVDD) that can occur if there is pressure being put on the spinal cord by a disk.
Until you can get an appointment with your vet today or tomorrow, I would get [a harness](https://www.petco.com/shop/en/petcostore/category/dog/dog-collars-leashes-and-harnesses/dog-harnesses) instead of a collar so as not to put any additional pressure on the area.
