My dog has diarrhea after amoxicillin. Is it normal? What about grass?

I hate to hear that Jersey is not feeling well. I do think the continuing diarrhea and regurgitation do indicate that she did not respond like she should have to the antibiotic. No knowing her full history, its hard to say what could be causing it but in puppies, parasites including Giardia are very common. You can also see infections in the GI tract, chronic foreign in bodies, organ dysfunction and food allergy as other causes. If Jersey is acting normal, has a good energy level and normal pink gums, I would recommend to make an appointment with her normal veterinarian to discuss next steps. The doctor may recommend a special diet, bloodwork and/or radiographs to start trying to figure out what is going on. She or he may also recommend special parasite testing depending on where you live. Feed Jersey small amounts of boiled white breast chicken meat and white rice. Make sure she is drinking water and keep her in a cool, comfortable area. If Jersey seems to be uncomfortable, has pale gums, seems weak or in distress, then you should go to the emergency clinic. Use your best judgement. I hope she starts feeling better asap!

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Vomiting can be caused by many different conditions including gastritis (upset stomach from eating something like garbage, raw food, bones, or dead animals in the park, etc.), pancreatitis, obstructions in the gut, as well as kidney/liver/metabolic diseases. Very often amoxicillin will do nothing to help the vomiting, and can make it worse as antiboitics are hard on the guts. I recommend feeding a bland diet of boiled/boneless/skinless chicken breast and boiled rice in small frequent meals (4-6 meals a day of 1/2 cup size meals). If the vomiting continues, or if Mui is lethargic or weak, then I would see a vet right away. If the vomiting stops and she is eating and acting normally then she is likely OK. I would not give any amoxicillin. Best of luck with Mui.

Riley’s stool looks a bit soft. This may be be from being on doxycycline as antibiotic associated diarrhea is fairly common. Your vet may be able to dispense a probiotic such as FortiFlora or Proviable that can help return the stool to normal. The blood may be due to stress colitis. Typically, metronidazole (flagyl) is an anti-inflammatory antibiotic for the gut that recommended for blood tinged soft stool, however as she just finished a course of antibiotics, putting her on probiotics and a plain boiled rice and chicken diet (unless she has an allergy to chicken) or a prescription Hills intestinal diet or Royal Canin Gastrointestinal diet for 3-5 days may be enough to allow the irritated intestinal mucosa to heal. Good luck!

Hi and thanks for posting! From the pictures, the stools appears to be somewhat firm, formed, but perhaps a little on the softer side which can be normal if this is his usual #2. Amoxicillin is an antibiotic which can cause softer or looser stools to form. if you are worried, you can always bring in a sample to your veterinarian for closer inspection.

It is a good sign that Panda is eating and keep down food even though it's small amounts, but it sounds like to me you are very concerned about him. It can take at least 24-48 hours to see some improvement in symptoms, and it can take a while for him to go back to eating normally. That being said, eating grass can be a sign of nausea, and if he's eating a lot, he may still be quite nauseous. I think that since you feel he hasn't improved and I can't see him in person, it's a logical next step to go back to the vet for further testing.

Poor Ace! The diarrhea could be due to many conditions including eating something he shouldn’t have, bacterial over growth, parasites or other even organ disease. It's likely the diarrhea and the not eating are related. If the diarrhea has continued beyond 24 hours, I recommend to have him examined by the veterinarian. With continued diarrhea, there are often bacterial shifts in the gut that will make matters worse regardless of the initial cause. Make sure to bring in a sample of fresh stool. The doctor will check him for parasites and bacterial over growth. Many times a bland diet can help and then a slow, gradual introduction to the normal food can be done. A bland diet can consist of 25% boiled white meat chicken and 75% boiled white rice. This should all be plain. A good diet in general is Royal Canin. It is low residue and highly digestible. Since Ace will not eat anything you offer, he needs treatment and medication to get and feel better. When pets don't eat well, they often don't drink as much as they should and can become dehydrated. Have him examined today. I hope Ace starts feeling better quickly! Please feel free to post any additional questions!

It is possible that she could be having a sensitivity to the antibiotic or this could be another complication to her upset tummy. I would make sure you are feeding her a complete meal then wait 15-20 minutes befor giving her the antibiotics. Also you may want to try feeding her only plain chicken (no bones) and rice as This is bland and easy on the tummy for recovery. If This doesn’t help then I would talk to your vet about a recheck. Your vet may want to give her an anti-nausea medicine, change her antibiotics or take X-rays if indicated. I hope this helps!
