I'm not really sure what is going on here with Hudson, because it only happens when we are out and about on walks. 1st time it happened was last weekend. We went out for a walk on one of the trails. He stopped shortly after we started out walk, squatted and had a normal bowel movement. We walked another 5 minutes (if that) and he stopped again, this time it was fairly normal but seemed kind of slimey-mucusy. Out next stop& squat it was very loose and by the end of the walk it was straight liquid. Later that day at home, totally normal. 2nd time was middle of the week, same thing, starts out normal, but quickly goes to liquid. 3rd was today and same thing, but progressed quicker Started normal, but by the second time, total runs. These have all been different trails, different times of the day, no correlation that i can see, except being out on walks. His poop is totally normal at home, even if it is during our walks around the property. Any ideas?
