My dog has a rash, vomiting, and diarrhea. Are these symptoms related?

Updated On September 23rd, 2025

Pet's info: Dog | Chinese Crested Hairless | Male | neutered | 10 years and 3 months old | 12 lbs

3 different vets said they weren’t sure what this rash was caused from. Wednesday he was vomiting, Thursday he started having severe diarrhea, confusion and stopped eating food, then Saturday evening is when I first noticed him starting to breakout. Im curious to know if the rash has any relation to the other symptoms. He is taking Flagly and CEFPODOXIME. The diarrhea stopped for 1 day, but is back now. The pustules have not gotten any better. I can’t afford an ultrasound. Any advice would help.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. The skin infection may be due to a resistant bacteria, so you may need to play around with various other antibiotics to see which works best. I would also recommend using a topical approach using the following products and see if this helps. As for the diarrhea, I would also add in a probiotic such as Fortiflora and test the stool for intestinal parasites. 1. Douxo PS Chlorhexidine combination shampoo 2. Malacetic conditioning spray 3. Essential 6 spot on by dermoscent Mojo is a breed where we do see skin infections and abnormal skin problems show up commonly. The diarrhea could be from something such as a dietary indiscretion, intestinal parasites, GI inflammatory disease, cancer, etc. You could use Tylosin powder (an antibiotic) and see if this helps calm down the diarrhea. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
