#1: Secretions from anal glands

If your dog smells like fish, the most likely reason is a secretion from anal sacs.

What are anal sacs?

Just inside and on either side of your dog’s anus are two small sacs. These contain sweat glands that produce a foul-smelling secretion. Dogs use these secretions to scent-mark.Now, secretions are released with the poop when your dog takes a dump. Secretions contain chemical information about the dog.That’s the reason why your dog is interested in another dog’s poop.But in instances when dogs happily meet, they get up close and personal. That is, by smelling each other’s butts.

The truth behind butt sniffing

What’s with butts? Why not smell the face? Or feet?But the butt, really?This brings us back to the secretions that anal sacs produce.Did you know that each dog has a unique scent? So when dogs sniff each other’s butts, they’ll know if they’ve met each other before.The scent of secretions helps a dog get information about other dogs.They’ll know if the other dog is a friend or an enemy. A male or female. Aggressive or friendly.Butt sniffing also helps dogs identify other dogs they haven’t seen in years. Perhaps your dogs got separated for a while.They only have to sniff each other’s butts. And through that, they get updated about each other’s lives.About the places they went to. The food they ate. What they did.Amazing, right?

First, there’s an abnormality in your dog’s anal sacs.Second, your dog has a soft stool. As a result, the anal sacs can’t be expressed properly when your dog poops.

Anal sac tumors

Anal sac tumors prevent your dog from completely expressing their anal sacs. This leads to firm and enlarged anal glands.

Abscesses and infections

A dog’s anal sacs can get infected. Without treatment, it could lead to an abscess.Abscessed anal sacs are painful. If not treated, your dog might need surgery.

Risk factors

Your dog smelling like fish is the first indicator of an anal sac disease. Look for other symptoms such as:
