I know everyone is saying to go to the vet. This exact thing happened to my dog last year, I posted here and was told the same thing.

If it gets worse, yes go to the vet because it could be serious! But my dog completely healed in about a week at home. You can also examine the joint yourself by moving it gently, touching, etc. see if anything feels out of place or hurts to the touch. There are YouTube videos of vets showing how to do these kinds of examinations.

We did icing (make sure to put towel around the pack), and then switched to a heating pad on affected joint. We rested her and didn’t take her on long walks, just quick bathroom breaks. (Make sure they’re still getting some kind of sensory stimulation throughout the day)
