My little one doesn't have watery poo, but it is soft. It is about the consistency of soft serve (think about that next time you get ice cream)

Occassionally, there will be mucus in her poo. She was at the vet and got dewormed last week, so I don't think it is worms, but I am not sure why there would be mucus in her stool. I haven't seen any indication of blood though! Just not completely solid poo and the occassional mucus. She eats regular and I noticed the mucus before I switched her food!

She does play with other dogs occassionally (I try to limit her interaction becuase she is kind of young still).

I called my mom when I first noticed it (she is a CVT) and she said I shouldn't be too worried about it, but it has happened since and, though the poo is a little more solid, the poo is looser than I would like it to be!

I've seen this many times in my boston, and she's always fine.
