Hello, sorry to hear about Penny. It sounds like she may have intermittent inflammation of her colon (colitis). This could be associated with parasites in puppies this young. Other causes could include viruses such as parvo. Finally, any dietary indiscretion (getting into something they shouldn't have) could lead to this as well. I recommend that Penny is evaluated by her veterinarian to check her stools for any worms. Additionally, she may be fed a bland diet for the next 5 days, which may be composed of plain white rice, skinless and boneless boiled chicken, and low fat cottage cheese. If this does not improve clinical signs, then she should be checked by her veterinarian. Hope this helps and best of luck.

Diarrhea and vomiting are usually signs referring to a intestinal problem. It could be due to dietary indiscretion (i.e. eating something that he shouldn't, diet change), parasitic infestation, inflammatory disease (IBD inflammatory bowel disease), bacterial diseases or viral diseases especially if Zoey is not fully vaccinated (i.e.: parvovirus). You could starve her for 4-6 hrs then provide bland food, boiled breast chicken and rice for the next 24 hrs (small and frequent meals) and monitor but as you spotted blood in her faces, she is not 100% in herself for few days now and she seems restless and uncomfortable, I would suggest to have her checked by your veterinarian to perform a complete clinical examination as soon as possible. Please collect a fecal sample in case your vet would like to run some analysis. Good luck and post again on the forum if you need further advices. I hope my answer was helpful.

Hi there! Sorry to hear that Zeus 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 Zeus 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 her on anti-nausea and anti-diarrhea medications. Good luck! Keeping my fingers crossed for your boy!

It sounds as your puppy 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 vomiting injection, antibiotics and a special food for a few days in order to get better.

Persistent vomiting and diarrhea in a young puppy is a significant problem that should be addressed as soon as possible. Some common issues that can cause this include the Parvovirus, ingestion of a foreign body (toys, plant material, etc), and other infectious / inflammatory conditions. I would definitely have him examined by your veterinarian today, making sure to tell them the symptoms on the telephone before you arrive. They may want to keep you and your pup out of the general waiting area until they have ruled out a contagious disease like the Parvovirus. Hope this helps and that Grayson is feeling OK.
