As faecal testing typically takes time to get results back, would you simply consider a normal faecal motion from a clinically normal dog, as a suitable donation?
“Puppies” is quite a broad classification. To implement this in practice, do you have a g/kg type of dose that you use. I appreciate it’s not an exact science.
Are there studies that could indicate a potential use for faecal transplantation in cases of acute haemorrhagic diarrhoea?
