Punterlab is 4 years old and has always had soft, sometimes very soft, poos and is on a light digestion kibble for this reason. Vet said that sometimes this is the way dogs are. Punterlab has had a couple of attacks of colitis after snaffling stuff in the bushes both of which responded to the usual vet medicines. The odd thing is that when he sometimes eats deer poo, or rarely horse poo, he becomes much firmer and 'normal'. Does this suggest something missing in his diet? Like veg?! He also eats grass but I see a lot of labs do this. Any ideas? Or shall i just let him gobble the deer poo.
