My puppy ate an expired sea mussel. Should I take her to the vet?

This is one of those situations where I would say you have a couple of options. Depending on how confident you are about your dog's digestive abilities, you have the option of inducing vomiting. It typically takes at least a few hours for food to move from the stomach into the intestines, so we still have time to prevent most digestion from occurring. If you decide to just take the wait and see approach, it's possible you might not see anything. The most common thing to look out for here would be diarrhea, vomiting, lethargy. Monitor feces for any distinct blackness or redness. Inducing vomit would likely prevent these from occurring if done soon. Because this is seafood and, by your question, I am assuming was spoiled, we cannot completely rule out the possibility of some pretty nasty viral and bacterial infections residing on the crab. If this were the case, it can cause pretty serious illness that would likely require hospitalization. This is not likely but worth mentioning. Hope this all makes sense.

As long as he is not vomiting repetitively or seems very lethargic i would recommend just monitoring him for now, do expect some diarrhea for a few days. if he shows severe symptoms you will need to take him to the vet for treatment, fortunately dog's stomach can usually handle expired meat much better than we do.

One thing I would be concerned about Sage eating scallops is that if he ate the orange part of them (the roe). The orange part contains toxins which can be fatal to dogs. If Sage did eat the orange part, you do need to take him into a vet immediately. This many scallops will cause GI upset, and there is a chance of infection from the bacteria of the raw scallops. If he did not eat the roe, I would monitor him for now. Likely you will see GI upset in the form of vomiting and diarrhea, and if you do see that, withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, the diarrhea continues on the bland diet, he stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

Even though it's expired, it can still caused Luna serious problems. You need to take her into a vet immediately. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck.

Poor Zee Zee. It's clear the oyster shell pieces have upset her stomach, causing the vomiting. The issue her is that these can cause a blockage. The best thing to do is take her into a vet immediately to get her checked out, as I can't say if she will be ok or not. A blockage is fatal without treatment. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck.

Dead marine mammals carry very nasty bugs, so I would not let my dog lick them. You do not need to take her to a vet unless she starts to vomit,, has diarrhea or develops a fever. Best take her temperature with a rectal thermometer tomorrow. Seals can get ill with canine distemper, so I hope your puppy has been vaccinated.

I would be surprised if you observe any severe ill effects from Pgmdad's seaweed ingestion. In the off chance she would become obstructed from the seaweed, you would likely note inappetance and vomiting within the next few days. Contact your vet if you note these changes. If she experiences any diarrhea, offer boiled white meat chicken and white rice in lieu of her regular dog food.
