Is a dog's anus looking bigger after anal gland expression normal?

Updated on September 23rd, 2025

My dog just got his anal glands expressed yesterday and his butt hole seems to be a lot bigger/open. Is that normal? We're the glands being full before what made it look smaller?

Hello. I think if his anal glands were indeed very full then I decompressing them could make his anus wider in diameter. However, if you have been lifting his tail more often to check his anus, this can also stimulate his anus to become dilated.

Other causes for a dilated anus could include him being sore from the expression of his anal glands or having to defecate. Walk him, and if he seems to be going to the bathroom normally, is not licking or scooting then he should be ok.

Hope this helps and best of luck.
