Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Harley!

Look closely at Harley's eyes...are they moving quickly side to side or rolling? If they are then he could be having a vestibular event. The most common cause is a middle ear infection (under the ear drum) that causes inflammation of the peripheral nerve that control balance. Other causes could be more serious: stroke, seizure, brain tumor, metabolic issues or bleeding that is causing weakness.

Harley should see your Vet ASAP this morning for an exam.

I hope this helps and I wish Harley the very best!
