Black tea is not a recommended cure for canine diarrhea. While generally regarded as a safe food, black tea contains caffeine, and excessive caffeine intake can cause insomnia, nervousness and even death, explains the Pet Poison Hotline. Chamomille tea, however, is recommended by the Smart Living Network.
Allowing a liquid-only diet consisting mostly of broths, juices and filtered water is the best approach, states the Smart Living Network. Make sure the dog has access to clean, fresh water and monitor closely for any changes. Once the dog is showing signs of recovery, slowly reintroduce solid food. Small, frequent meals of a bland, low-fat nature such as rice and unseasoned hamburger or skinless chicken breast are best, according to DogAware.com. Plain canned pumpkin can be included to help absorb liquid in the system and add fiber to help firm the stool. Avoid pumpkin pie mixes, because they typically contains additional spices that could irritate the system.
If diarrhea continues for longer than two days, or is accompanied by other symptoms, such as vomiting, black, tarry stools or bloody stools, consult your veterinarian, states DogAware.com. Painful or bloody diarrhea requires immediate attention. It is important to remember diarrhea is a symptom rather than an illness, and could be a sign of a more serious problem, states the Smart Living Network. It is always better to identify the cause rather than just attempt to treat the symptom.
