Try pumpkin along with extra protein like cottage cheese to firm it up for 2-3 meals. Antibiotics will only help if she has something else wrong with her.

Animals can be really sensitive to food changes. Our pup is extremely sensitive.

It’s only a strong antibiotic if they give you a strong dose. Flagyl (metronidazole) is a very good antibiotic. It’s worked for both my dog and my cat when they had bacterial gut infections.

Further worsening of the stool situation may indicate that it’s more than a bacterial infection, or it may be a different TYPE of bacteria. Definitely get the stool sample to the vet as soon as possible.

Till then, keep up the rice. Also, BOILED ground beef and chicken are good for upset tummy pups.

Plain canned pumpkin, NOT pumpkin pie filling. I used that with the kittens and it helped a LOT.

@oracle:  I gave mine rice when they had diarrhea and after a couple of feeds it actually made them worse – almost like it was cleansing them too much. I’ve found egg helps.

If the vet prescibed it then start it, if its a puppy vets generally prescibe metronidazole for colitis, especially if you noticed any blood.


If you would rather not start it, rather than adding stuff to the diet, you need to fast the dog (water only) for twelve hours and reintroduce very bland food like boiled lean breast of chicken and rice.


However if the vet examined the dog and prescibed these antibiotics I dont see why you wouldnt start them?

We are currently giving it to one of our cats for the same reason. He hates taking it, but doesn’t seem to have any other problems with it.

We still don’t know what caused it, actually. The vet gave us a pill and a half (hubby forgot what they were so I don’t know), the Flagyl, and special low cal/low fat diet food. They also took a stool sample which came back normal.

The day of the vet visit, we found blood in the stool (sorry for TMI), but right after that, the diarrhea cleared up and we haven’t noticed any since.

@oracle:  Flagyl is commonly used for diarrhea in pets. Any ongoing GI upset can easily cause an imbalance of “bad” bacteria to good, and it works very well for this. It can also be used to treat Giardia, a type of parasite in contaminated water sources.

If you aren’t comfortable with the vet’s treatment plan, call her and ask about your other options. Boiled chicken breast/rice is the bland diet of choice (even boiled, ground beef can still be a little too greasy/fatty and cause other issues). Pumpkin is not generally recommended for loose stool because it can soften the stool on its own if you give too much.

I would recommend talking to your vet again and voicing your concern. They are there to help you formulate the best plan.

Have your vet check a stool sample. When I got my kitty she was having loose stools. I wasn’t sure if it was bc I was giving her a different kind of food and it was upsetting her tummy so I took her in. Turns out she had giardia and was put on Flagyl.

We had a similar problem when we first adopted our dog and it took a good few weeks for her poop to get normal.  We started with plain boiled chicken breast and white rice and when it seemed to be doing better, we switched to her food.  She had one bout since then, we used the same tactic and she returned to normal within a few days.

If you don’t want to medicate her yet, I’d put her on a diet of boiled chicken breast and rice and a tablespoon or two of pumpkin (plain, unseasoned). If she doesn’t show any improvement in a day or two then I would give the antibiotic. How long have you had her? If you just got her I personally wouldn’t change her food immediately, that’s a lot of stress and change for a dog in a new environment. Let her settle down for a week or two and then do the food change.

I personally wouldn’t give the metronidazole.  One of the common side affects is gastroenteritis!  (specifically diahorrea and cramps)
