Your Dog’s Breath: A Fishy Tale

Does your dog’s breath have a whiff of the sea? You’re not alone. Many dog owners ask, “why does my dog’s breath smell like fish?”

Unpleasant fishy breath in dogs can be attributed to a variety of factors. Let’s delve into the most common ones.

Firstly, your dog’s diet could contribute to the fishy odor. Some dog foods and treats contain fish products, which can linger on the breath.

Secondly, poor oral hygiene can lead to fishy-smelling breath. Bacteria and plaque build-up can create a foul odor, reminiscent of fish.

Lastly, dogs have anal glands that secrete a fish-like smell. When dogs groom themselves, this scent can transfer to their mouths.

Worried about your dog’s fishy breath? Here are some solutions:

Consider altering your dog’s diet. Opt for quality dog food without fish ingredients and monitor any changes in breath odor.

Implement a consistent oral hygiene routine for your dog. Regular brushing and dental treats can help keep bad breath at bay.

If the fishy breath persists, a vet check might be in order. Your vet can rule out any underlying health issues contributing to the smell.
