Her tummy is really hard and she seems to be in a bit of pain . Think she may be constipated . Just wondering what is the best thing to give her to make her "Go" ..? Suggestions please ..?
Don't give her anything without asking your vet first - it could be something much more serious than constipation; obstruction due to a foreign body or an intussuseption, for example.
You could ask the vet about the lactulose when you visit. Unless you know what it is best not to treat. there could still be an obstruction even after going to the toilet, it depends where the obstruction is. no amount of latulose will shift that.
