When discomfort may be part of the picture
A dog looking or biting toward its tail may be responding to discomfort. It is not safe to conclude that spinning is purely behavioral because the dog is young, playful or a breed associated with the behavior.
Several problems can look alike
VCA lists injury, itchiness, parasites, anal-gland discomfort and neurological problems among possible contributors. AAHA also notes joint or spinal pain. This is a list of possibilities for a veterinary assessment, not a checklist that identifies what your dog has. A dog may have more than one contributing issue.

Visible information is useful; interpretation is separate
If you can observe safely without manipulating the tail, note visible hair loss, licking, chewing, skin change or an injury. Record when you first noticed it and whether it seems different now. Do not examine a painful area by force. Use your veterinarian's instructions for handling and care, especially if your dog is guarding the area.
Do not run a home treatment experiment
The possible causes require different assessments. This site does not recommend medicines, parasite products, anal-gland procedures, bandaging or doses. Do not use an apparent response to a toy or distraction as evidence that there is no physical problem. A clinician can choose the appropriate examination and tests.
Make the appointment easier to use
Bring the date of onset, a list of changes you have noticed, relevant veterinary instructions already received and any short video captured without provoking the behavior. Keep your observations distinct from what another person told you. Ask the clinic how to send a video securely rather than uploading it to a public page.

Do not wait for a perfect record
Sudden onset or increased frequency warrants a veterinary conversation. Injury, self-trauma, distress or neurological concerns need prompt help. This resource cannot set a safe waiting period for an individual dog. Contact your veterinary team, and follow its advice about urgency.
