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