Hi, sorry if this is a bit stomach churning but am really worried about my 12 week old puppy? He has been to the toilet outside for a poo which was looser than normal,but wasnt to concerned, however a couple of minutes later he ran out again, and when I went out to check found small pool of mucus( size of 2 pence piece) which he had obviously just pooed out? There was nothing solid,just mucus of a brown and red colour? He seems fine in himself but am really worried about this and not sure wether to contact emergency vet? Has anybody else experienced this?
