My 14 year old male Shiba Inc has started peeing in the house, usually when he is within a few feet of me or my husband. This is net new behavior. He is otherwise healthy with no known health issues.

Sudden changes in behavior can sometimes signal a health issue, and accidents in an elderly dog can be caused by a number of things. Bladder infections can cause sudden accidents in the house, while changes to the muscles and nerves around the bladder may lead to incontinence-type accidents with dribbling or small puddles happening. Cognitive changes in elderly dogs (similar to human dementia) can also sometimes cause a pet to "forget" their training such as potty training, leading to accidents. It is a good idea to schedule a veterinary exam to see if any of these could be a possible cause and to find a treatment plan that helps.

Fecal incontinence can happen for a variety of reasons but if your dog is unaware that this is happening then this suggest a neurological disorder. I recommend you have Blue Boy checked out by your veterinarian as soon as possible.

Wow, Bambino has got to a very senior age. It's hard to say if this is due to a medical problem (old dogs produce more dilute urine, and larger volumes of urine as the kidneys age), or as it sounds more like behavioral. It could also be senile changes and loss of house training- a bit like human seniors who develop Alzheimer's. Make sure he's not left for extended periods of time, let him outside before you leave and right when you return. You may need to let him outside when you're eating as well. Your vet will probably suggest blood work and urine testing to rule out kidney or bladder problems.
