Most Likely Conditions Based on Your Answers:

Your answers are an indication that there could be a serious medical condition that needs your veterinarian’s attention. What could be causing your dog’s incontinence? Several conditions can cause an increase in drinking and … peeing, including:

1. Kidney Disease

Kidney disease is one such circumstance that would result in a dog drinking and urinating more as well as having accidents in the house. Kidney disease may be caused by infection, kidney stones or just general old age.  The most common symptoms are:

Many senior dogs have some degree of kidney disease (this means that their kidneys aren’t filtering out toxins from the blood efficiently). Two of the most common symptoms of failing kidneys are excessive thirst and increased urination.

But you’re likely to see both of these as symptoms of several other conditions, so don’t jump to the conclusion of kidney disease just based on this.

It is MORE common to see additional symptoms when the kidneys are involved, but this doesn’t ALWAYS happen. This is because a build up of toxins in the blood (because the kidneys aren’t filtering them out) results in systemic illness.

Kidney disease can be treated with many different medications depending on the underlying cause, which your vet will choose based on your individual dog. Your dog may also need intravenous fluid therapy to flush out excess urea in the blood.

Your veterinarian is the best person to determine the most appropriate treatment.

2. Diabetes Mellitus.

Diabetes can occur at any age, but it is more likely to affect senior dogs (Most dogs who develop this condition are 5 or older at the time of diagnosis).

Symptoms include:

  • Excessive thirst
  • Increased urination
  • Increased appetite
  • Weight loss
  • Lethargy
  • Repeated UTI’s

Two very common symptoms of diabetes in older dogs are increased thirst and increased urination. So, if your older dog is peeing in the house and seems to be extra-thirsty, diabetes could potentially be the reason why your old dog suddenly started peeing in the house.

This is a condition that you need to get under control otherwise it can cause serious health problems for your dog. It can even become fatal if left unchecked. If you notice these symptoms, get your old dog to your vet asap. Diabetes needs to be treated with insulin, which will probably require injections twice a day, as well as a diet change.

3. Cushings Disease

Cushing’s disease is a hormonal disorder that occurs due to your dog’s adrenal glands over-producing a natural steroid hormone called cortisol. This is because of a (usually benign) tumor that grows in the pituitary or adrenal gland.Cortisol is a stress hormone, so an overproduction of this results in your dog being in a constantly stressed state.  This can produce all kinds of different symptoms, including increased urination.

Symptoms include:

  • Excessive thirst
  • Frequent urination
  • Increased appetite
  • Lethargy
  • Thinning coat/hair
  • Swollen belly
  • Panting
  • Loss of muscle tone/strength

There are two types of Cushing’s disease: pituitary dependent and adrenal dependent, depending on where the tumor is. Both forms of Cushing’s disease can be treated medically with either trilostane or mitotane, however, adrenal dependent Cushing’s disease is better treated with surgery.

Please note that there could also be other reasons causing your old dog to suddenly start peeing inside.

This is why we recommend that you consult with your veterinarian to determine correct diagnosis and next steps. It is also important that your vet rules out other serious conditions that could also cause your old dog’s peeing inside the house (such as diabetes or Cushing’s disease).

Other causes

The three conditions listed above are the most common causes of excessive drinking and urination in the house, but there are many other conditions that could cause this. These include but are not limited to liver disease, Addison’s disease, toxicity and neoplasia (cancer).

What to Do Next?

If you’ve noticed a pattern in your dog drinking more water and urinating more (and being aware of it), then you should have them checked out by your veterinarian.
