My puppy is lethargic, whimpering, and has black poop after neuter.

Poor Hank! Hank could be lethargic with soft stool for a variety of reasons, including parasites, viruses, etc. The changes you are observing in his eyes could be a result of dehydration. Hank should see his vet for an exam to make sure there isn't anything more serious occurring. Until you can take him to his vet, you can try offering a bland diet of boiled white meat chicken and white rice.

Something's not right - Copper should be recovering normally at this point. I'm worried about a potential reaction to pain medication, or even a completely unrelated problem, such as parasites or a bacterial or viral GI infection. I would get him seen as soon as possible - he needs to be examined to determine the exact cause, and treated with appropriate medications.

Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite and lethargy can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. I recommend that you have Gracie Mae evaluated by your veterinarian for further assessment and treatment. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!

These symptoms are always concerning in a puppy. If Muffin did not have a complete set of vaccines when he was younger, parvo or distemper is a possibility, even without blood in the stool. Hypoglycemia or liver disease could also cause these symptoms, and could be a concern if your Husky is only 10 pounds at 6 months. I would recommend that he be checked out by a vet ASAP.

I am sorry to hear about Sheena. These symptoms are concerning especially in a young dog. Lethargy and inappetance make us concerned about ingestion of a foreign object and parvovirus if your dog hasn't had all her vaccines. Certain parasites can also cause these symptoms. Combined with dark runny stool (a dark tarry color can indicate bleeding in the upper GI tract), these signs indicate that she needs to see a vet today for an examination. They will likely check the stool for parasites (bring a sample of you Gabe one) and do a parvotest and may recommend an X-ray.

Pain after neutering does occur, and your vet can give you pain medication for him if they haven't already. After neutering, some dogs can be tired and want to rest a little more than usual. Keep an eye on the stitches where the surgery was done, and make sure they don't become red and swollen. Do not let your dog lick the stitches. Your dog likely didn't poop until this morning because they weren't allowed any food for 12 hours before the surgery, so they wouldn't have anything to poop out. Butt scooting can also indicate parasites, so if his worming isn't up to date, I would get worming tablets from your vet. If the incision site becomes red, swollen, and warm to the touch, I would contact your vet right away for an appointment. It is also okay to give your vet a call if you are concerned about your dog being in pain, and see what options they can give you for pain relief.

Based on your description of the black stool, lethargy, and decreased appetite, I am concerned that June may be very ill. The black stool could be blood in the stool, which could be caused by parasites, change in diet, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body, or a mass/growth in the gastrointestinal tract. Please make an appointment to have June seen by a veterinarian as soon as possible, as blood in the stool can lead to anemia, and can be very dangerous if left untreated. In the mean time, if she is not eating well, you can try boiling boneless skinless chicken in water, shredding the chicken, and feeding her small amounts of the resulting chicken broth and cooked chicken once it has cooled. I recommend taking in a fecal sample from June to your vet as well, as that may aid them in making a diagnosis. Good luck, and I hope she feels better soon!
