Ask a vet 24/7: Puppy Eats Green Tomato & Dane Consumes Methigel

Have you ever gotten home after a vet visit and realized you forget to ask them something important about the discharge instructions or home care? Of course, this scenario typically happens after the vet hospital is closed and lines of communication are severed.

Below are real questions asked of VetLive veterinarians! Hopefully, the answers can help you in an emergency.

Question: ‘We have a 15-week-old pup. Yesterday morning he got into my parents’ tomato plant and picked off a green tomato about the size of a large grape. He ate about half of the tomato before we were able to get it out of his mouth. We didn’t think too much of it until he had diarrhea later in the afternoon. I went on the Internet, did some research and found out the leaves and stems of the tomato plant are toxic, as well as unripe green tomatoes. He is showing absolutely no signs of being ill other than the diarrhea, he is not lethargic, he’s eating, drinking and being himself. It was just the fruit and no stems or leaves. Looking online I could not find any information on the quantities of green, unripe tomatoes that would cause anything serious. Do you think we are safe to just be monitoring him closely?’

Answer:

I do have some largely positive news for you and your pup. It takes large amounts of the unripe green tomato fruit to cause any real harm, and the most common first symptom you would see is severe GI upset, vomiting and diarrhea.

You mentioned he does have diarrhea. If he still has this today, I would recommend you take him in for a vet checkup as the toxic ingredient can have cardio toxic effects. The toxin isn’t well absorbed systemically, so even if it causes GI signs, it usually is limited to those unless large quantities of the toxin are ingested.

Tomato plants contain alpha tomatine, a glycoalkaloid. It is found throughout the plant but especially in the flowers and leaves. Concentrations are high in young green fruits but decline markedly as a result of metabolism during maturation and ripening. Concentrations in plant parts arranged from highest to lowest are as follows: Flowers, small stems, leaves, calyces, small immature fruits.

Based upon the info, if he only ate about half of a grape sized unripe tomato, I am surprised to hear he has had diarrhea at all. It is possible it is from something else entirely. Still, with dogs being mischievous as they are, I would keep an eye on him and if the diarrhea continues today, I would advise you to be cautious and pursue a vet visit.

Question: Carson got into a room and ate a 4 oz tube of Methigel. What should I do? Carson is a Great Dane weighing 122 lbs.

Answer:

Email 1: Good news mostly! If Carson ate the entire tube this would be only double the prescribed dose for a dog his weight. I want to check with a colleague on this, as there is very little available with this medicine relating to overdosages in dogs.

Methionine does not seem to cause overdoses in dogs according to the literature search I’ve done. It would be worrisome in cats, but there is nothing available about this being dangerous for dogs specifically. The one thing that can happen is metabolic acidosis but the dose would need to be higher than simply double the dose.

Like I mentioned, the dose he consumed should be fine but I will verify with a colleague and get back with you.

Email 2:I did the calculations based upon his weight (and double checked them with a colleague). Eating the entire tube would actually be his daily dose. It is typically given every 12 hours, and the whole tube is what he would need in one 24 hour period.

I read a report on a dog (Lab) who ate a two pound bucket of methionine so I just want to put it into perspective. That bucket is an overdose (though the dog suffered no ill consequences) but the 4 oz tube should be fine for a dog Carson’s size. He may experience diarrhea.

Please let me know if you notice anything unusual but I suspect the remainder of your evening will be uneventful.

Can Tomatoes Be Bad For Your Dogs?

Tomatoes are part of a family of vegetables called nightshade. They contain toxic substances that are harmful to your dog. The green parts of the tomatoes contain a highly concentrated amount of solanine and tomatine.

Besides, the solanine in the tomatoes decreases as they begin to ripen—this is why it is advised to feed your dogs the ripe tomatoes. You have to ensure that your dog never ingests the stems or leaves of the tomato plant.

Similarly, it would be best if you avoided any unripe tomatoes. If your dog has any of the parts mentioned above, it can develop tomato poisoning.

Tomatine Poisoning

Generally, tomatoes contain small amounts of solanine and tomatine. Feeding your dog a high amount of tomatoes can give them tomatine poisoning. Still, it is unlikely that your dog will consume enough tomatoes to cause serious complications.

Regardless, a small number of tomatoes given to puppies can cause tomatine poisoning due to their small size. It is essential to remain vigilant when feeding your puppy tomatoes. Thankfully, there are very few cases of tomato poisoning in dogs, and those cases are not usually fatal.

What To Do When Your Dog Is Showing Signs of Tomatine Poisoning

It would be best to take your dog to the vet as soon as it shows symptoms of tomatine poisoning. Your vet can perform fluid therapy to treat the poisoning. Fluid therapy uses electrolytes to treat any dehydration caused by tomatine poisoning. It is also effective in helping the dog’s body flush out the toxins. The vet can administer fluid therapy to your dog through the abdominal wall, veins, or under the skin. This all depends on the needs of your dog.

Similarly, your vet can induce vomiting in your dog to expel any pieces of the tomato plant left in its stomach. Your vet can also use activated charcoal to restrain any toxin left in the gastrointestinal tract before the dog’s body can absorb it.

When inducing vomiting in your dog is not possible, your vet can perform gastric lavage. In gastric lavage, a tube is placed in the dog’s stomach to flush out the toxins. In cases where the dog has difficulty breathing, the vet can prevent asphyxiation by creating an emergency airway.

Can Your Dog Be Allergic To Tomatoes?

The answer to this question is yes. Your dog can be allergic to tomatoes, even the ripe ones. Some common symptoms associated with an allergy to tomatoes in dogs include itchy skin, coughing, and hives. Most dogs suffering from an allergy to tomatoes also experience gastrointestinal issues. When you notice that your dog has an allergic reaction to tomatoes, remove them from their diet.

Similarly, there are rare cases where an allergic reaction in your dog can cause anaphylaxis. If this occurs, you need to take your pet to the vet immediately.

Can Your Dog Eat Canned Tomatoes?

No. Canned tomatoes contain a high concentration of sodium. It can cause excessive thirst, nausea, increased urination, and dehydration in dogs if taken in high amounts. The best thing to do would be to feed your dogs fresh, ripe tomatoes.

Can Your Dog Eat Cooked Tomatoes

It would help if you prepared any cooked tomatoes your dog will eat. Cooked tomato products bought from the store contain other ingredients aside from tomatoes that can harm your dog. These ingredients can be artificial flavors, sugar, or salt.

Similarly, try to avoid feeding your dog tomato sauce. Tomato sauce often contains onion and garlic, which can be unhealthy for your pet.

What Quantity of Tomatoes Can Your Dog Eat?

It would help if you fed your dog small quantities of tomatoes. Analyze the size of your dog before feeding it tomatoes. Smaller dog breeds should eat fewer tomatoes than larger dogs. But large dogs should also eat tomatoes in moderate quantities.

Whatever the size of your dog, introduce the tomato little by little to their diet to see how they react to it. Do not exceed the quantity limit even if your dog loves tomatoes
