Here's the situation:
Here's sort of a schedule of whats been done. All regular shots and dewormers are given on schedule to the day. Diarrhea is generally all day and he cannot hold it at night, and will mess in the house. When no diarrhea, he has not pooped in the house. No pee in the house, to date.
Moose is 100% supervised, he is not eating anything outside and he is not getting ANY food scraps or treats of any kind. Fed twice daily, no snacking.
Early May: Moose comes home (12 weeks old), no food change (purina pro plan sensitive skin &stomach)
Late May/ End of may: Moose develops watery/mucousy green diarrhea. Vet is called immediately. Fecal test done showing over growth of clostridium. He is given amoxicillin twice daily. Diarrhea clears up within 24 hours, and remains clear for the 7 days he is on the amoxicillin. 5-7 days after treatment is stopped, diarrhea returns but is now far less green and more dark brown.
**through the next 3 months, fecal tests are done almost weekly, showing nothing but a lot of dead bacteria, and live bacteria, nothing specific that would be causing any problems, dewormers also given occasionally**
By this time it is middle June we try 14 days of amoxicillin (vet says maybe it wasn't taken for long enough, but wants to stick with the antibiotic because it was previously effective). Same story, but 4 days after treatment is stopped, diarrhea returns, but not as bad (dark brown, no green no mucous). This time probiotics (refrigerated) were given in between each dose of antibiotic.
July: Probiotic use continues, we try 1 week of Metronidazole (Flagyl). This works only slightly -- stool is still soft and poorly formed, but it is not a cow patty. After this, food is slowly changed to Purina Prescription Diet EN. This makes things worse and out of frustration, I feed him homemade deboned salmon and pumpkin. Stool is semi-normal after this meal. Perhaps this is a food allergy? Feed him the rest of the salmon and pumpkin while slowly adding in Taste of the Wild puppy ocean formula. Responding OK to dog food, but still not great. He is still having bouts of diarrhea inside overnight (still dark brown and pudding-like). After full bag, we try Natural Balance LID Sweet Potato & Salmon. Some improvement, but not relieving overnight messes. Best response to food so far. No food change since.
August: Diarrhea has returned in full force (dark brown and pudding-like). Vet suggests tylan powder (2x daily 1/8 tsp, for one month). Moose eats this medicine with some pumpkin. Meal is given with probiotic and crushed digestive enzyme tablet. Diarrhea clears up after first dose and meal (immediately). One week later digestive enzyme and probiotic are replaced with Dogzymes powder sprinkled on food (Both digestive enzyme and probiotic). Stool consistency improves even more. Tylan powder use continues.*
**this "digestive enzyme" is plant based (I think), not from the ground pancreas of another animal**
First week of September: Moose is weaned off Tylan powder. First three days he is given tylan once a day, then every other day for four days. Then Tylan is stopped (9/6)
One week later (9/12-9/13): Stool becomes soft in the afternoons, normal in the morning. No inside mess. 9/13- evening poop is VERY soft, starting to pile but still semi-formed. This is basically the progression of stool that I've seen before with him when the diarrhea starts. To prevent diarrhea overnight, I gave one dose (1/8 tsp.) of Tylan powder. Message has been left for Vet who I will hopefully hear from by tomorrow morning.
The first month was basically meat and rice only for about two weeks, and intermittently thereafter after particularly bad days. Stopped because it didn't really help, rice came out completely undigested.
We are fairly sure that nothing is lodged. It would have presented alternative issues after this long, according to the vet.
Energy level 100% generally every day since i've had him (other than sleepy-puppy days during which he grows like a weed).
