Feste and Chance both have fairly loose poop. Puck, who is 30 -35 lbs. and eats the same food (Diamond, Large Breed), has what I would consider normal consistency. I've noticed that the big boys' seem to get looser when it gets really hot or if they have been on a very long walk (2-4 miles). Since I've not had Feste or Chance during colder weather yet, I'm waiting to see if that has any effect. According to the vet, all the tests are normal and there are no issues so he left it to me to either tolerate it or keep trying different foods. I pretty much have learned to live with it (hoses down easily), but I do keep an eye on it for any major changes.
