Pet's info: Dog | Shiba Inu | Male | neutered | 1 year and 7 months old | 23 lbs
I got a dog a few months ago a Shiba Inu. He is a year and 7 months old. Occasionally, his butt leaks a liquid. It smells almost like copper or metal. I am just wondering how to stop this or what it is as I do not want this smell all over my couch and floor. He licks his butt sometimes when it happens so his breathe can smell like it too. What is this? How do I prevent it?

This sounds like she is leaking anal sac fluid. The anal sacs are like scent glands in a skunk. They are on either side of the anal opening. The foul smelling fluid usually comes out when they defecate or sometimes when they are scared or hurt. If she’s just started doing this the sacs are probably over full. Please take her in to have them emptied and make sure they are not infected. Many small dogs need the anal sacs expressed every few months to prevent impact ion and infections.

It sounds like the liquid is coming from her anal sacs. These are two small sacs located on either side inside the anus that release this smelly liquid to help lubricate the feces as they pass. The anal sacs are a normal part of a dog's anatomy, and the smell is terrible! Sometimes these can get impacted, or dogs can have overactive anal sacs. I would have Mali checked out by a vet for this issue. They may be over-full and need to be expressed to stop the leakage. Good luck, I hope this helps!
