Is it normal for my dog's rear end to have a metallic smell sometimes?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Female | spayed | 68 lbs

My dog has a rust/metallic potent smell that I believe is coming from her bum area. It o ly comes and goes once in a while. I didnt think much of it at first because I thought maybe she licked something rusty outside but now I am more concerned.

I bet you are smelling anal sac/gland fluid. They are scent glands dogs have just inside there rectum. They are supposed to express a small amount every time they defecate, but sometimes they will leak if they get startled, or bark forcefully. If this is an occasional problem it is normal. If she is scooting or licking her rear end or otherwise acting uncomfortable then she should be evaluated by your veterinarian to make sure she doesn’t have an infection. Best of luck and thank you for using Pet Coach.

    This problem may be definitively due to an anal gland inflammation/infection.
    Even though a picture would help me to give you more definitive answers, a check up is necessary to confirm this clinical suspicion and treat appropriately. Anal glands must be expressed and antibiotics may be needed.

    Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.
