Can I give my dog cranberry juice for a urinary tract infection?

Can a dog UTI cure itself?

How can I comfort my dog with a UTI?

Ensure your dog has a comfortable bed to lie in and plenty of fresh drinking water. Your pet may wish to be outside more than usual, as it has the urge to pass urine frequently.

Your presence is likely to be very comforting to your pet while they feel unwell.

If your pet is particularly uncomfortable or has a high temperature, then pain-relieving medication may also be given.

Sometimes there may be stones or debris that accumulates in the urinary tract, meaning infection if more likely.
