As a caregiver, you know all too well that your furry friend can sometimes come back from their outdoor escapades smelling less than fresh. One odor that you may have noticed, that is particularly off-putting, is a strong fish-like smell. So, why do dogs smell like fish when they come in from outside? Let’s dive in.
1. Anal Glands
The primary reason a dog may smell like fish is due to their anal glands. These two small, pea-sized glands are located just below your dog’s tail and can emit a strong, fishy odor.
The Purpose of Anal Glands
Dogs have many ways of communicating with each other, and one of those is through scent. Anal glands produce a unique scent that dogs use to mark their territory and identify each other. When your dog defecates, these glands release a small amount of this potent liquid. It’s perfectly normal, but it does smell strongly of fish.
Problems with Anal Glands
Sometimes, these glands can become blocked or infected, leading to a build-up of this fishy-smelling liquid. This can cause your dog discomfort, and they may scoot their bottom along the ground to try to relieve the pressure. If you notice this behavior, it’s a good idea to take your dog to the vet as it could indicate a problem that needs to be addressed.
2. Diet
Another reason your dog might smell like fish could be their diet. Many commercial dog foods use fish as a primary ingredient due to its high protein content and beneficial oils.
Fish-Based Dog Food
While fish is good for your dog, it can make them smell, well, fishy. If your dog’s diet is primarily fish-based, it’s not uncommon for them to have a slight fishy odor. This smell can be even more noticeable when they’ve been outside and are hot or wet.
Changing Your Dog’s Diet
If the fishy smell is particularly strong or bothersome, you might want to consider changing your dog’s diet. Look for dog food that is high in protein but uses other sources, like chicken or beef. Just remember to make any changes to your dog’s diet gradually to avoid upsetting their stomach.
3. Rolling in Fishy Smells
Dogs love to roll in strong-smelling things, and if there’s something fishy-smelling outside, chances are your dog will find it. This is a natural behavior for dogs, but it can leave them smelling rather fishy.
Why Dogs Roll in Smelly Things
This behavior dates back to their wild ancestors, who would roll in strong-smelling things to mask their scent from predators. While our domesticated dogs don’t need to worry about predators, the instinct remains.
Preventing Your Dog from Rolling in Smelly Things
Preventing your dog from rolling in smelly things can be a challenge. One option is to keep your garden clear of anything that might smell fishy. Alternatively, you could try training your dog to come to you on command, so you can distract them if they start to roll in something smelly.
4. Dental Problems
Dental problems can also cause your dog to smell fishy. This is because bacteria in your dog’s mouth can produce a foul-smelling gas that smells like fish.
Recognizing Dental Problems
Common signs of dental problems in dogs include bad breath, difficulty eating, swollen gums, and discolored teeth. If you notice any of these signs, it’s best to consult with a vet.
Treating Dental Problems
Regular brushing can help prevent dental problems, but if your dog already has a dental issue, they may need professional treatment. This can involve a scale and polish, or in severe cases, extraction of the affected teeth.
5. Skin Infections
Finally, skin infections can cause a fishy smell. These infections are often caused by yeast or bacteria and can produce a strong, foul odor.
Recognizing Skin Infections
Common signs of skin infections in dogs include redness, swelling, itching, and a foul odor. If you notice any of these signs, it’s best to consult with a vet.
Treating Skin Infections
Treatment for skin infections will depend on the cause, but it will usually involve a course of antibiotics or antifungal medication. Regular bathing with a medicated shampoo can also help to manage the symptoms.
