No one can answer what to do with your dogs, we can only answer based on our experiences and what we would do. It concern me that both your dogs have the same issues, at the same time. Since it was Purina and Freshpet, and its affecting both dogs, I would be highly suspicious of something else. IMO, its highly unlikely for two dogs in the same household to have the exact same issue. That leaves me with questioning the safety product being used, and then environmental/.
In other words, if you are sure the food is stored correctly, without contamination, bowls are cleaned regularly etc, then my mind would wander to another cause..
Cleaning product in the household? Drinking contaminated water source out doors uch as mud puddles, streams etc.. Virus? Did they go anywhere they could have been exposed to something?
