Dogs typically need their anal glands expressed only when necessary, not on a fixed schedule. Most dogs naturally empty their anal glands during defecation, so routine manual expression is usually unnecessary
. However, some dogs may require manual expression more frequently due to individual differences or health issues. The frequency can vary widely:
- Some dogs may need it only once or twice a year
- Others might require expression every 4 to 8 weeks if they have recurrent problems
- In more severe cases, some dogs need expression as often as every 5 to 10 days or weekly
Signs that a dog’s anal glands may need expressing include scooting their rear on the ground, excessive licking or biting of the rear, a strong fishy odor, swelling or redness near the anus, and difficulty or discomfort while defecating
. If these signs appear, a visit to the vet is recommended to assess and express the glands if needed. Over-expressing anal glands can cause irritation and dependency, so it is best to express them only when there are symptoms or a vet’s recommendation
. For dogs prone to anal gland issues, a common guideline is to have them checked and expressed every 3 months, but this depends on the individual dog
. In summary, the frequency varies by dog:
- Most dogs: no regular expression needed; glands empty naturally.
- Some dogs: every few months or as symptoms arise.
- Dogs with recurrent issues: every 4–8 weeks or more frequently as advised by a vet.
Regular monitoring for signs of discomfort is key to determining when expression is needed
