Thank you for submitting your question regarding Benji. The first thing to determine is of he is regurgitating or vomiting as they are due to different causes. Vomiting is accompanied by signs of nausea, retching and abdominal contractions. Regurgitation is the passive upbringing of food. The puppy may be surprised the the food the food or water slipping up. Vomiting and diarrhea (or soft stool) are common in young puppies. This can be due to a diet change, intestinal parasites or stress from an environment changed. Regurgitation is typically caused by a severe congenital anomaly when evident in a very young puppy. He will need to see his veterinarian to determine the cause of his signs. I hope this information helps!

    These are not really related. With his aggression that you are noticing I would recommend first neutering him. I would also recommend a trainer to work with him and you. The trainer should be able to identify triggers. With regards to him not eating and getting sick. The most common reasons are them getting into something they were not supposed to. If he is still not eating tonight or tomorrow morning I would bring him to a veterinarian. I would recommend feeding boiled chicken and white rice also. A one time vomit isn't something too concerning. This becomes an emergency when they continually vomit, have diarrhea with vomiting, have blood in either, lethargic and on top of everything not eating. I hope Chip feels better soon and thank you for using Petco Pet Education Center, formerly Petcoach.

Hello! My 11 week old puppy is a yorkie-chon and he has been throwing up his kibble today(he only eats a small amount). I made sure he didnt have a cough, his waste is solid, drink plenty of water, and is active and is acting normal. I just want to m
Poor Benji! If he's only vomited once or twice, it is best to keep an eye on him. You can also offer a bland meal of boiled rice and chicken to help settle any minor GI upset. Small breeds are more prone to issues such as hypoglycemia, so making sure Benji is fed several smaller meals throughout the day instead of larger ones may help, and may also decrease vomiting so he isn't eating too much all in one meal. If he continues to vomit, or shows other signs of illness in addition to it, a vet visit is best to rule out other issues such as illnesses, parasites, foreign body ingestion, etc that can also cause vomiting.

Good morning my dog is 9 months old this morning his poop was loose with blood in it and it was yellowish green..and he really wasn't eat yesterday can you please help me with so I'll know if I have to take him to the vet or it's something I can take
It sounds as Benji is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti nausea injection, antibiotics and a special food for a few days in order to get better.

My puppy is 3 months old, he had his first puppy shots on the29th. I recently changed his dog food the day before yesterday and we have been giving him rawhides (bully sticks and new treats) he has been fine but he has had more frequent bowel movemen
Thank you for submitting your question regarding Pj. I'm sorry to hear that he is experiencing vomiting and diarrhea. If a dog is going to suffer a vaccine reaction, it typically occurs the same day as the vaccination. So this is likely unrelated. He may be experiencing GI upset secondary to all the new treats. I would stop those for now. Being so young and small, he should see his veterinarian if symptoms persist. In the meantime, encourage him to eat and drink small amounts. It will be easy for him to become dehydrated at his size. I hope this information helps!

My dog is about 2 months old has been vomiting,has diarrhea, he wont eat or drink any water. Hes been like this all day. His poop has a very strong odor ,sort of like tuna. Im wondering what is going on and what to do , im very worried.
These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hi! I just got a Border Collie last night. He is 2 months old and I woke up to him throwing up. A few hours later I fed him again and shortly after, he threw up a few times. His poop seems normal and his throw up is just his food. What could it be?
Hi there and thank you for using Boop by Petco to address your concern. If he does not seem lethargic, I would withhold food for 6 hours and then initiate a bland diet as outlined below. If Bernie become lethargic, continues to vomit or develops diarrhea I would strongly recommend that you have a veterinarian examine him to help better determine what the cause could be. I would want to make sure he does not have a foreign body intestinal obstruction from something he ate, parvo virus, etc. Testing such as a parvo test and abdominal x-rays can help rule these out. He may just have a dietary indiscretion from something he ate or a new food / treat you gave him as well. I hope this helps! Please let me know if you have any other questions or concerns and I would be happy to help you out further.

Hi there! Sorry to hear that PJ is not feeling well. The clinical signs you describe are concerning when they occur in a puppy as they can be seen with serious gastrointestinal infections such as Parvovirus. Other possibilities include intestinal worms and dietary indiscretion, among other possibilities. The sooner these conditions are treated the better the outcome tends to be. For this reason, I recommend that you have PJ evaluated by your veterinarian to check for these possibilities and to start therapy based on findings. At the very least they can address dehydration if present and start him on anti-nausea medications. Good luck! Keeping my fingers crossed for your boy!

I got a new puppy on Saturday. When I gave him his dry food, he ate it really fast and then threw it up. I started hand feeding and that seemed to work. Now, he's throwing up clear watery bile and has foamy diarrhea. I tried giving him some can pumpk
He is adorable! He could have an infection, parasite, or an upset stomach from a change in food. I don't think he needs to have hundreds of dollars of test but it would definitely be a good idea to have your vet run a fecal test including Giardia to make sure he doesn't have a parasite. Your vet can prescribe a dewormer based on the test results and other medications to help control the vomiting and diarrhea. You could also add a probiotic to his diet, like Fortiflora or Proviable and see if that helps, too. Feeding him a bland diet, like boiled chicken and white rice may help, as well. Hope he feels better soon!

My new puppy won't eat anything and hasn't eaten in two days. He has vomitted and has diarrhea, and will only drink water. He's been laying down all day and only gets up to go to the bathroom. Should I be worried? or is this him getting used to his n
Unfortunately, this is not normal behavior for a young puppy and is pretty concerning. At less than two months old, your puppy needs to eat regularly or he risks having low blood sugar, which can cause serious health problems. Vomiting is not typically caused by stress and all these signs make me worry about a more serious illness. Please have him seen by a veterinarian right away because his lack of appetite and vomiting are very serious.

So I got home and my puppy golden retriever threw up and he had diarrhea. His threw up was like brown tan color and his poop was light brown. He’s very down, he doesn’t want to play or anything. I’m very worried and don’t know what to do.
I would take Opie into a vet immediately. He's just over two months old, and he will not be fully vaccinated yet so my first concern is parvovirus. He could also have a GI illness, may have eaten something rotten, or could have a foreign body. Whenever a young puppy is both vomiting and having diarrhea, it's time to see a vet right away. The vet can diagnose what is causing his symptoms, and can treat him. Best of luck.

My 8 month old puppy has had diarrhea & threw up once early this morning. We can hear his tummy making noises & he doesn’t want anything to eat or drink. Not sure what to do for him. He is up to date on all of his shots.
Diarrhea and throwing up can have many causes. It is basically a problem with the stomach and intestines caused by a food over sensitivity, eating something that does not agree with the dog, intestinal parasites, bacterial infection, viral infection, the weather, food change, stress, etc. I would put Milo on bland food for a day or two, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to his regular food slowly over a few days. If this does not clear up the diarrhea or if the vomiting increases, or if he gets lethargic, he needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.
