What is a good laxative for a dog?

If your dog is constipated, add a bit of plain canned pumpkin (nothing added) to each meal. About 1 tablespoon for every 10 pounds, but adjust to the individual dog.

jess is correct. pumpkin is awesome for both doggie constipation and doggie diarrhea.If it doesn't work, my vet says a little mineral oil (but it can be aspirated so putting pure petroleum jelly on a paw and letting them lick it off is safer), but not on a regular basis.Milk of Magnesia (saline laxative) is safe for dogs, but it can have extreme effects, so only use in extreme cases
