My dogs have diarrhea one by one, but no other symptoms. Why?

Pet's info: Dog | Chihuahua | Male | 4 years and 7 months old | 9 lbs

Hello, one by one my 3 dogs have had terrible loose watery stool. No other symptoms. My oldest dog, 8 yrs had it about a week ago for a day and a half. Then, my youngest, 3 yrs, had it for about 2 days and it's now going back to normal. My 4yr old started the diarrhea last night and woke up with it today. They all had an appetite. Just bad diarrhea.

I recommend you put them all on a bland diet for a week (like boiled chicken and rice) and give them all Fortiflora probiotic for 2 weeks (each box will treat 2 dogs for 2 weeks). One packet on the food once a day. https://www.chewy.com/purina-pro-plan-veterinary-diets/dp/50029 You can buy it on Amazon too probably with free shipping as opposed to chewy's website. This was just so you can see what product I am talking about. It is by far the best probiotic out there. This way you can treat them all without them passing it back and forth. If this does not help you may have to take a fecal sample to your vet to have it tested for parasites. Hope this helps. If you have more questions please post again! Best wishes!
