For approximately the last year, our now 2 year old Labrador Retriever has had a problem with her anal glands. We've taken her to the Vet 2-3 times to have them 'expressed', but within a few weeks the smell is back. If you haven't smelled this before, trust me it is foul.
The interesting thing however is that this appears to have started when we switched her off "puppy food" (formulated for puppies) to adult food (Turkey as the main ingredient).
It is also interesting that since we have switched her to a different food (Beef as the main ingredient), the frequency has nearly diminished to none.
The bottom of the can that I keep her food in still contained the turkey based food, because I decided to switch before she was completely out, and also didn't want to dump all the existing food in the garbage in the event switching didn't work.
Well, we've reached the old food in the can, and now the smell is back.
Is it plausible that switching her to Beef instead of Turkey (the same manufacturer of food), could have impacted the decreased presence of the anal gland issue?
