Her picture is adorable!
Ohhh, I know how upsetting bloody colitis is, you have my sympathy.
When my pups were at their sickest, we fed them plain strained beef baby food with white rice at room temperature (the vet said cold food could irritate their colons.) And their water had to be at room temperature also; we kept a pitcher of tap water at room temp.
I am also very careful about washing floors, to always rinse twice with water. We do not use any lawn chemicals or fertilizers in the backyard. I do not walk them in my neighborhood because of the lawn chemicals everyone else uses
(makes my pups sick.)
Does the vet know what the cause is yet, and if not, are they actively looking for the cause?
What do you normally feed her when she is well? My Geordie gets diarrhea from chicken, so I have boiled ground sirloin beef in water and rinsed it, then mix into white rice for a bland diet.
My two had multiple problems causing the colitis. They chewed acorns and mulch which was just terrible! I could not even walk them on a leash in the backyard when the acorns started coming down August through November. (We finally sold the house and moved away from the huge oak trees!!!)
They also had worms and whipworms, which took a few treatments to get rid of. The vet finally had me give India a double dose of Panacur, which I felt terrible doing. I think that worms are sometimes difficult to diagnose, but I don't understand why.
And the lingering colitis was finally diagnosed as Clostridium, the vet had to culture their stool samples and send them to a lab, they had an overgrowth of it in the intestines that was releasing toxins. The vet gave us a bottle of Tylan powder for them. We had to sprinkle 1/16th teaspoon on their food every day for several weeks.
While they were recovering, we paid for a home visit by a veterinarian behaviorist. She did not feel it would be possible to train them from chewing acorns. But she did make a suggestion which I will always thank her for regarding worm prevention - we took them off the Revolution monthly drops, and put them on monthly Interceptor tabs and Frontline Plus drops. They have never had worms since then, knock on wood.
