Should I go to the emergency vet?

Go now if the dog is straining and producing no urine, or the belly is tight and the dog is vomiting. A male dog that postures and passes nothing may be blocked. A dog that is a day late after a bone-heavy meal and is otherwise bright can be walked and offered water, then seen if nothing passes.

How much will treatment cost?

Straining with little or no stool needs an exam to separate constipation from a urinary blockage and from diarrhea that has already emptied the colon. Films are added when the dog is painful or has not passed stool for more than a day. Ask for the estimate before radiographs.

Can I treat this at home?

Offer water and a short walk, and call the same day if the dog is vomiting, bloated, or producing no urine. Do not give a human laxative. A bone-heavy diet is a common reason the stool turns white and hard.
