My dog has clear, watery, mucousy diarrhea with green algae.

I am sorry to hear about Jo! Being that she was from a shelter it is quite possible she has GI parasites, which could be worms or protozoa like Giardia or Coccidia. I would recommend bringing Jo and a stool sample in to the vet for an exam. In the meantime you can start a probiotic for dogs (available at pet stores and vet offices and online) which can sometimes help.

Diarrhea in dogs can have many causes, including food intolerance or allergies, intestinal parasites, dietary indiscretion, bacterial or viral infection, stress colitis, among others. Some dogs with sensitive stomachs can get diarrhea from simply changing foods suddenly or having treats. I recommend that you talk with a vet about Arrow's constantly changing stool consistency. They can rule out easy things like intestinal parasites. They may recommend a special diet or have other recommendations on feeding.

With these pups, there is always a potential for parasites or bacterial overgrowth to cause the symptoms. I would recommend to get Parks in for an exam and to have the stool checked for parasites. That is usually a good sign if you don’t see any more blood, which is what I’m concerned you were seeing in the stool. It’s better to be safe and also to make sure he doesn’t have any parasites to spread to his new human family. There are other causes for blood in the stool as well and these can vary from a new diet to internal organ damage. The first step is to rule out the most common things. I hope this is helpful and please feel free to post any additional questions.

Stress, change of diet, parasites, etc can cause diarrhea. It can be normal for a dog that is new to the home. I would recommend giving him bland food for a couple days, such as boiled chicken and rice. If no improvement, contact your vet.

Poor pup! Diarrhea with no obvious cause can definitely be frustrating. If no parasites were seen on her fecal exam and she's acting normal otherwise, then it may be a food allergy or intolerance issue - I have seen this a number of times in puppies with diarrhea who tested negative for all the usual suspects, but did very well with a diet change. You can try feeding her plain boiled chicken and white rice for the next 3-5 days to see if the diarrhea resolves - if so, then she may need to stay on a special, easily digestible diet such as Hills i/d or Royal Canin GI diet.

Hi there! Although dogs can get diarrhea from worms, there are other reasons why, including bacterial infections, or even dietary indiscretion (eating something out of the ordinary that they shouldn't), that can cause it. From the description of the mucous, it could very well be colitis - or inflammation of the colon or large bowel. Also, fleas carry tapeworms, so sometimes the over the counter de-wormers don't take care of those. You can try a fast of 12 hours of no food, and very little water. After that period of time, 1/3-1/2 of their normal portion of food in the form of boiled or steamed lean protein such as chicken breast or ground turkey (no sauce or seasoninng) can be introduced. If the diarrhea seems like it's improving, or it stops, every 12 hours you can increase the portion little by little until it's back to the normal portion of food. If the diarrhea is not improving, both dogs should be evaluated by their veterinarian. It is important to make sure that the dogs are not getting too dehydrated from the diarrhea (as even though they may be drinking, they lose way more fluid than they can take in sometimes with diarrhea). The veterinarian can also give them some medications to help with the diarrhea, like, for example, some antibiotics to help re-balance the bacterial populations in the gut. At any time, if vomiting starts in addition to the diarrhea, I always advise to have the pet(s) evaluated immediately, because this can indicate an intestinal blockage, or a severe gastrointestinal infection or diffuse inflammation. All of those issues need to be addressed immediately. If the diarrhea does improve with the bland diet, I always advise to feed it until there is 48-72 hours of normal, solid stools. Then, you can transition the dogs back to their normal diet, gradually, over the course of 5-7 days (as switching too quickly can actually cause diarrhea).

Stray cats can pretty nasty parasitic infections. I would check to see if the vet ran a fecal examination + a Giardia test. Both of these can pick up on many parasites that can cause persistent diarrhea. However, if these tests were already done and were negative, then additional testing may be needed to find other not so common causes of diarrhea like the one ran by Idexx. Http://www.idexx.com.au/pdf/en_au/smallanimal/reference-laboratories/diagnostic-updates/realpcr-canine-feline-diarrhea-panels.pdf Any pet with diarrhea should be on a broad-spectrum dewormer, probiotics and potentially and antibiotic for treatment regardless of any of the tests mentioned above. I would suggest going back to the vet for additional treatment and these additional tests if not done already.
