Why Is My Dog Peeing in the House
This page is educational reference material for preparing questions. A licensed veterinarian examines the animal, makes the diagnosis, and sets the treatment.
Indoor urination causes in dogs: UTI, marking, anxiety, aging, and medical conditions. Solutions and when to see a vet.
Understanding This Symptom
The first clue is usually subtle, and it is usually behavioural. Owners who learn the baseline pick it up days before a vet would. This page covers the most common causes, warning signs that indicate an emergency, and what you can expect at the veterinarian.
When to Seek Emergency Care
Any of the following should prompt an immediate ER trip: open-mouth breathing, a painful swollen belly, collapse, uncontrolled bleeding, seizures, or suspected ingestion of a toxin. Observation here costs lives.

Should I go to the emergency vet?
Go the same day if the new accidents come with blood, straining, a huge increase in drinking, or an intact female who is also lethargic. A dog that squats and produces no urine should be seen now.
How much will treatment cost?
The clinic will want a urine sample and an exam before anyone calls it a behavior problem. Bloodwork is added when the dog is also drinking more. A behavior consult is a later cost, after infection, stones, and diabetes are off the list.
Can I treat this at home?
Clean the spot with an enzymatic cleaner, note the time of day, and measure water intake. Punishing the dog hides the signal. A sudden change in a previously housetrained adult is a medical question first.
