A dog smelling like fish is most commonly caused by issues with their anal glands. Dogs have two small anal sacs on either side of their anus that produce a fishy-smelling secretion used for communication. If these glands become blocked, impacted, or infected, the secretions can emit a strong fishy odor. Other potential causes include dental problems, urinary tract infections (UTIs), skin conditions such as yeast infections, or certain diets rich in fish or fish oils. In female dogs, urinary tract infections or vaginal infections can also cause a fishy smell. It's important to have a veterinarian evaluate a persistent fishy odor to rule out serious health issues.
Why Dogs Smell Fishy
- Anal Gland Issues : Anal glands can become blocked or infected, leading to a painful, fishy-smelling discharge. Signs include scooting, licking or biting the rear, and discomfort during defecation.
- Diet : Fish-based food or supplements like fish oil can affect body odor and breath.
- Dental Problems : Infections in the mouth can cause bad breath with a fishy undertone.
- Urinary Tract or Vaginal Infections : UTIs or vaginal infections, especially in female dogs, can produce a fishy smell.
- Skin Conditions : Yeast or bacterial infections can also emit unusual odors.
What to Do
If a dog smells fishy consistently, it’s advisable to:
- Check for signs like scooting or discomfort.
- Have a vet examine the anal glands.
- Rule out infections or dental issues.
- Avoid self-treating without professional guidance, as some conditions require antibiotics or other veterinary care.
This fishy odor is a common but potentially serious sign and should be evaluated by a veterinarian to ensure proper treatment and care.
