Hey Patrick........just to cover all bases....
In older dogs it's not uncommon for problems to arise in their urinary tract. A Urinary Tract Infection (UTI) being the most common.
One of the symptoms is inability to hold their urine.
Whether or not Owens Walter is experiencing any of this - might be worth considering a supplement such as this one (and there are many others). Just read the reviews and you'll learn more about it's benefits.
Good luck!
