At her age there are several things it can be. Your vet can collect a urine sample to check for a urinary tract infection. They can always draw some blood to check her kidneys and blood sugar and for Cushings disease. All these can cause an increase in drinking and urination which will lead to accidents. If all of that is normal, than she may be getting incontinent and they have medication for that also!

    A 13 year old dog is like and elderly person. He may not be able to hold the urine as long, he may be too stiff and painful from arthritis to want to go outside, or he may have mild senility and forget his housebreaking. I recommend a veterinary exam and urinalysis to determine if there is a medical problem causing this. Otherwise I would take him out more often and confine him to a smaller area when you are not supervising him. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for your dog.
