Why Are Oysters Bad for Dogs?

Although oysters come with a rich nutritional profile, you must cook them appropriately to maximize their benefits for your pet’s health. Here are some reasons to consider why oysters can be bad for your dogs:

Allergies: Although not all pets are allergic to seafood like shellfish, you must exercise care when you are feeding these to your pet for the first time. Hence, always start small to avoid risks and to know your pet’s compatibility with oysters. 

Raw oysters can harbor harmful bacteria and viruses like dinoflagellates and salmonella. This condition can lead to paralytic shellfish poisoning (PSP) in dogs. 

Symptoms of shellfish poisoning in dogs: 

  • Unstable walking
  • Excessive drooling 
  • Weakness 
  • Vomiting

Ingested toxins: Species like oysters are said to be filter feeders prone to pick up pollutants in water. Hence, any oyster that grows in unhealthy water can accumulate toxins. In turn, these toxins can affect your dogs if consumed. Therefore, it is always good to prefer canned oysters. 

Overfeeding: Oysters have to be fed in moderation to your pet. Too many oysters in your pet’s diet will make them sick. 

Oyster shells are pretty rigid and tough. However, ingestion of these shells could render gastrointestinal blockage for your pet.

Fried/Smoked oysters are inappropriate for a dog’s diet as they contain excessive fatty contents. Similarly, smoked oysters contain additives that, when consumed, can cause an allergic reaction in your pet. 

How Many Oysters to Feed Your Dog?

  • Baking

Further, refrain from smoking or frying as this can enhance the fatty contents.
