It seems extremely stupid that there's no fine for leaving horse poo on the road/footpath when dog fouling attracts a fine.
compare accidentally treading horse shit into your house, with accidentally treading dog shit into your house. cow and horse shit is just half-digested grass, I wouldn't particularly want to roll around in it but it's really not that unpleasant. dog shit is gross.
In a perfect world I would not (accidentally) tread any kind of shit into my house. Human, dog, horse, bird, insect (???), mollusc, etc. But I understand that dog shit and horse shit are different.
