First of all, it is clear that dogs can't eat oysters, not only oysters, but also many seafood products. Because the salt content of oysters is too high, dogs can't eat anything with too high salt content, otherwise it will lead to skin allergies. If the dog just eats a small amount of oysters by mistake, then we don't have to worry too much, as long as we pay close attention to the symptoms, it doesn't matter if there is no serious problem. However, if allergic symptoms are found in the later stage, they should be sent to the pet hospital immediately for special doctors to deal with. If we eat for a short time and eat too much, for the safety of dogs, we can immediately go to the pet hospital and ask the doctor to induce vomiting. If skin hair loss occurs, you should fast other salty foods, have a light diet, and eat more nutritious dog food such as protein to promote hair regeneration.
