I have a 5 year old spayed Weimeraner bitch who has suddenly become incontinent nearly always at night. She was treated with antibiotics for a week for an infection which didn't work and then with incurin for two weeks which also had no effect. The vet didn't advise any increase in dose or any other type of tablets but for an appointment for blood samples and a scan. My dog doesn't appear to have any other symptoms and seems otherwise normal. Do you think the vet should have tried an increased dosage of incurin or tried propalin which I have read can help before taking these steps?
