My pig is lethargic, not eating, and vomiting. What should I do?

Updated On September 23rd, 2025

Pet's info: Farm Animal | Pig | Male | neutered | 1 year and 4 months old | 200 lbs

One of my kune kune pigs, which is normally very healthy and friendly, began showing a lack of interest in eating today, has been demonstrating lethargy, and threw up a light cream colored substance two times in a small amount. I just wanted to see if you have any suggestions until I can get him to his normal veterinarian office tomorrow. Thank you.

There are many things that can cause vomiting in pigs. I suggest you just hold him off food until you can get her seen by your vet. That way his stomach can rest. Have water available for him to drink but don't force him to take in water.

    I am so sorry to hear about Cheese! I would check all over her body for any pain/swelling/bruising. Move her legs around and press on her belly to check for sensitivity. If she will allow you to look in her mouth look and see if there is food inside the mouth. If you see no little bits of food that is a sign that she has not been eating and is concerning. If you aren't sure if she has been urinating and having normal bowel movements I would clean the cage and then observe her closely today. If urine and bowel movements don't appear normal or she isn't eating or drinking, or if the lethargy continues she should see a vet right away as these little guys can decline quickly when they are ill.

    I would recommend taking her to the vet tonight if you can. Usually by the time a guinea pig shows us they are sick they have been sick For a while and just hiding it. If you cannot tonight I would offer his his favorite treats to make sure he is eating and take her to the veterinarian tomorrow.

    Thanks for reaching out about your guinea pig. Being lethargic is a signs of being ill, so a veterinary visit is recommended to assess and provide a diagnostic/treatment plan. Providing some heat support could give some comfort but does not replace the need for a veterinary visit. Continue to offer food and water through a syringe. Monitor fecal production and urination. Good luck.

I have a sick pig he won't eat or drink an he's vomiting I'm not sure what I should give him or need to do
Bacon should be examined by your veterinarian to diagnose illness or injury. Once a diagnosis is made, the appropriate treatment can be administered. Do not wait to see if he improves. Dehydration is a very real concern that can complicate any underlying condition.

Hi I have 4 pigs (I think almost a year old, almost ready to be butchered) only problem is that 3 out of 4 are lethargic and hardly eating or drinking and won't move around. Normally they yell at me to feed them and are very loud and noisy and they j
As you probably already know if your pigs are sitting there quietly when you try to do something to them then it's safe to say that something is probably very wrong. I would first try and get us a temperature on them see if they are carrying any sort of fever and I would also look to see if they have any sort of skin lesions. Regardless of what the cause of the current problem is I'd say that it is probably not safe to eat or butcher these animals at the moment. You can contact a local veterinarian that deals with swine and see what they think but in all likelihood they will probably want to administer an antibiotic. If they do then you will have to wait the withdrawal prior to butchering and selling these animals for meat. I would also be curious to know if they have any sort of diarrhea as many swine illnesses cause this.

I went to feed my pigs . I was out there for 30 min she pucked about 5 times. I have 2 and they both pucked. It was clear and it also came out of their nose . I feed them pig pellets and cracked corn .
Vomiting is serious in pigs. You need to call the vet for a visit. This could be a viral infection, bacterial infection or a gastro-intestinal problem. Take their temperature if you can, and tell the vet on the phone. They will need an exam.

my 1 1/2 week old piglets are vomiting yellow foam from their mouth. what is the cause and what can I do? should I give them any vaccine or medicines?
Hi Your piglets need to be seen by a vet. Vomiting can be caused by parasites, viruses or bacterial infection in piglets. Vomiting can cause lots of dehydration, so try and see if they'll eat. Your vet can find them medication to help.

Hello! Our 1 month old baby pig seems to have a cold & usually she loves running around but right now she seems sort of tired and sleeps more. I usually feed her milk & she enjoys it alot. What should I do or feed her? Also what would be the average
Pigs tend to run hotter than people and a normal temp is around 101.5-102.5 degrees Fahrenheit. If she's lethargic, not wanting to eat as much, and also has nasal discharge, I'd be worried about something underlying such as a respiratory illness which can affect piglets. Having a vet take a look, especially if she isn't improving, is best. In the meantime, keeping her eating her regular food, and keeping he warm may help keep her comfortable until the cause is found.

She has threw up 8 times in a few hrs her vomit was white now yellow hasn't ate or drank since yesterday morning do I need to take her to vet?
If she is lethargic as well as not eating or drinking, she should be seen by your veterinarian. An exam and diagnostics (blood work, xrays) can be done to diagnose the cause. At the very least, supportive care (IV or subcutaneous fluids, anti emetics, etc.) may be administered. If she is bright and alert, you can try withholding food for 24 hours. Allow small, frequent amounts of unflavored PediaLyte. Resume feeding a bland diet in small, frequent amounts. Once the vomiting ceases, transition slowly to her regular diet. If the vomiting does not stop or if she develops other symptoms then she will need to see your veterinarian.

My dog ate 15 thick slices of raw bacon yesterday and I took him to the vet. They induced vomiting but he only vomited 5 of the pieces up. Last night he ate dinner but he only pooped small pebbles last night after dinner and has not pooped since th
Fast him until tonight. Offer small amounts of water or unflavored PediaLyte throughout the day. Consider feeding him a bland diet in small, frequent amounts for the next few days then transition slowly to his regular diet afterwards. Monitor for vomiting, diarrhea, loss of appetite, lethargy or abdominal pain. These are symptoms that should be addressed by your veterinarian.

Hello! My mini pig escaped about two nights in a row, and today i found her vomiting what she ate this morning. She looks skinny but yesterday she was looking okay. Her partner which escaped too, looks okay and is not vomiting, he is eating okay too.
Hi there. It sounds like she may have eaten something she shouldn’t have or may have been exposed to a toxin. I would have her checked by a veterinarian and also feed her some pedialyte to hydrate her. Best of luck and thanks for using Pet Coach!

My blue heeler ate some old pork and 30 minutes later was shaking drooling, fevered, vomitting, diareha 24 hours ago. Shes not throwing h Up or pooping anymore but cant eat, lethargic please help
Sadie sounds very sick, and she needs to see 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.

We have a sow with 8 week old piglets, she isn't eating has weak back legs and a red udder, what is the cause and treatment?
The piglets should be weaned by now. Do not let them suckle her anymore. By now they have teeth and will injure her teats which can then develop mastitis (inflammation of the mammary glands). Redness, pain and not eating, weakness, are all signs of a severe mastitis and she will need to be seen by a veterinarian. Your vet will likely prescribe anti-inflammatory medication and, if there is a bacterial infection, antibiotics.
