If your dog has diarrhea and a particularly foul odor, it's often due to issues like food problems, parasite infections, or contagious diseases.

Food-Related Issues Causing Diarrhea in Dogs
1. Dietary Problems: Consuming cold or spoiled food can easily cause diarrhea in dogs. It's advisable to stop feeding these items immediately. Introduce probiotics, such as those from My Doctor, to help balance their gut environment. Furthermore, unsuitable foods like spicy items, spoiled kibble, raw seafood, or pickled products can cause gastrointestinal intolerance and lead to diarrhea. Switch to fresh, healthy food, avoid giving any unsuitable items, and consider a one-day fast to allow their stomach to rest. Improper diet is a common cause of smelly diarrhea in dogs.
Parasitic Infections and Canine Diarrhea
2. Parasitic Infections: Internal parasites such as roundworms or coccidia can cause damage to the intestinal lining, resulting in diarrhea. If you suspect a parasitic infection, prompt deworming is highly recommended to tackle the root cause of smelly dog diarrhea.
Contagious Diseases and Diarrhea
3. Infectious Diseases: Infections from viruses like coronavirus, parvovirus, or canine distemper can trigger diarrhea, often accompanied by symptoms like lethargy or unusual body temperature. Veterinary intervention is needed right away to start suitable treatment and manage the disease causing dog diarrhea.
Other Possible Reasons for Dog's Bad Smell
Besides these, your dog may be particularly smelly due to not bathing for a long time or being exposed to dirt and grime. It's important to pinpoint the source of the odor before determining the solution. If the bad smell emanates from the coat, bathing your dog is highly recommended. In case ear mites cause the foul smell, use ear drops recommended by My Doctor or other appropriate medication to get rid of the ear mites and improve the smell of your dog. Remember that maintaining your dog’s hygiene is vital for their overall health and smell.
