Hi everyone, I’m hoping for some advice before going back to the vet again for the third time. I have a \~9–10 month old laboratory rescue beagle, about 20 lbs, dealing with intermittent diarrhea and mucus stools.

Key info:

	•	Fecal test negative

	•	No blood

	•	Appetite and energy normal

	•	Stools range from soft-serve to mucus, sometimes straining or squatting with little output

	•	Comes and goes over several days

Possible factors:

	•	Brief accidental switch from adult food to puppy food

	•	Stress/environment changes (rescue background, visitors)

	•	Possible food sensitivity (currently avoiding chicken)

What I’ve tried / considering:

	•	Bland diet (rice)

	•	Slowly transitioning food

	•	Probiotics (FortiFlora / Proviable / Native Pet)

	•	Fiber or digestive enzymes

	•	Hydration

The vet mentioned antibiotics (metronidazole), which he was on for 5 days and it improved but now he is back to where he was. Since the fecal was clean and he’s not acting sick, I’m hoping to manage this with diet/probiotics first if possible.

If anyone has experience with lab beagles, GI-sensitive dogs, or mucus stools with a negative fecal, I’d really appreciate tips on what helped. I just want him comfortable and not in pain 😞

Thank you!

I’ve also attached a pic of my baby boy, Poe. 💙
