My German Shepherd has chronic diarrhea with bright red blood in stools and mucous material. He has been in the vet a few times and the problem resolves for a few days and then returns again. He is on a low fat diet. He has been in metronidazole, enzyme for the intestine, but nothing resolves it. Im worried!! Please help!!

Hi Jessica,


How old is your boy?


How long does he have this?



What is the name of the food he is eating?




Customer: replied 8 years ago.
Bruce is 14 months old. He started with this 6 weeks ago. PURINA EN, gastroenteric canine formula.
Expert:  Terri Riba replied 8 years ago.

Hi Jessica,


I am so sorry Bruce is not felling well.


It sounds like he has Colitis:


Of course protozoan parasites cannot be over ruled:





Purina EN isgood but lets try him on the Canine colitis diet:


Purina DCO - has a fiber content between maintenance foods and w/d - it is around 7% fiber (w/d is around 15%)

---Eukanuba Optimum weight control


Here are a few other web pages with useful information:


Omce he is better try a small amount of boiled chicken with all fat drained off, chop meat , or baby food with no onion, beef, turkey, etc add cooked white rice or infant rice cereal.] @ two tablespoons per meal. This is to rest his GI tract.



Dogs get dehydrated and hypoglycemic very easily from diarrhea.

Add unflavored pedialyte to his water 50/50 to hydrate him and balance his electrolytes.

Put a drop of pancake syrup on his tongue to raise his blood sugar in case he is a bit hypoglycemic. That should perk him up.

Do not allow him to drink a lot at a time If he throws up water, he can lick ice

Keep him on that very light diet of boiled chicken or baby food with rice cereal for 48 hours after the stool is normal.

Also give him one teaspoon a day of plain yogurt to keep "good" bacteria in his system.

If he develops any abdominal pain, bloating, constipation or cannot keep anything down he needs to be reseen by a vet.


Please let me know how he is doing. I will always be here for you


I hope your boy feels better very soon..

Best wishes,

can you tell me why his digestive system is like this. Knowing that he does not have parasites (checked a weeks ago in the vet) and having the strict diet he is having.
Expert:  Terri Riba replied 8 years ago.

Hi Jessica,


Some dogs have colitis due to high end breeding. Their digestive system just takes a while to accept and process foods.


Give him a probiotic if he is not on one already.

The one that seems to work best is Culturelle.


I hope he better very soon,
