Why Is My Dog Having Diarrhea All The Time But Still Acts Fine And Wants To Eat And Play?

Most gastrointestinal upset in dogs is mild and self-limiting.  If it lasts more than 2-3 days, if dogs stop eating or drinking, or start vomiting they need to be examined by a veterinarian.
If your dog still has diarrhea tomorrow she needs to be examined by a veterinarian and have a fecal analysis performed.  If she is experiencing weight loss or dehydration she needs to be examined at this time.
You can try feeding a bland diet--boiled chicken or hamburger and boiled rice--this is easily digestible and helps settle the stomach and intestines.  Also feed canned pumpkin (fiber) at a dose of 1/2-1 teaspoon twice daily depending upon the size of your dog.  Give plain yogurt (a good probiotic) at a dose of 1/2-1 teaspoon twice daily depending upon the size of your dog.

If the diarrhea is not accompanied by other symptoms like blood in stool, fever or vomiting then wait for 24 hours and if it does not stop than take him to vet to avoid dehydration. Diarrhea in dogs can be due to parasite, food allergy or change of diet or any intestinal infection.

I have a 4 year old bassett hound he is allergic to everything so is on a immune therapy treatment, he has diarrhea all the time I have always fed him a fresh food diet of chicken and rice and biscuit my other basset has the same no problems I just don't no what to give him he is ok in himself I think the treatment he is on does not help but he has to have it has anyone got any ideas on what I could feed him ....

This can be caused by inappropriate diet, internal parasites, infections, metabolic diseases and toxins.  If your pet is bright and alert and otherwise well and showing no other symptoms the general approach is to starve for 24 hours.  Allow water during this time, you can also provide lectade to maintain hydration.  After 24 hours introduce a bland diet of cooked chicken and rice.  If all goes well you can wean him back onto his normal diet.  You should also worm your dog.  Adult dogs should be wormed every 3 months.

Noy unless the dog is not eating or has vomit give hard dog food it will harden the poop

My dog had this I don't remember what they said it was  but it could be kennel cough so take it to the vet immediately

That is so sad you had to put your dog down. I'm so sorry. For the question, you could try sensitive stomach formulas of dog food. Our boxer started having diarrhea and we just switched the food. Also, don't feed him any other foods...like table scraps :)
