So... I have recently started taking my puppy for walks - we go to our local park and he is off lead once we get there. His poo in the past three/four days (ie pretty much since the park outings started) has been:
a) copious in quantity - I mean, it seems like a LOT of poo for a small puppy
b) fairly frequent - 6 ish a day. (He is on three meals)
c) not as firm as it was - not totaly liquid by any means but not picking cleanly up off the floor all the time.
He came to us on Burns, had toothpaste poos, then we slowly swapped to Fish4dogs but he was drinking (and therefore weeing) absolutely loads on it and weeing in crate at night as it was too salty for him (lots of you will have seen my mention of this on puppy thread - complete with taste tests 
). So we went to JWB. Which he loved at first (and poos fine) but seems to be slightly less keen on now.
Is it likely that the poo changes have been caused by the park outings, him eating things he shouldn't etc?! Or his food? Surely if he was okay at first it shouldn't now suddenly disagree with him....
(btw BARF isn't an option as we don't have the space - live in London with half size freezer, and I couldn't get to the butcher every day).
Once again - thanks a lot!
