Incontient adult dog

Hello! At first, I wanted to warn you that I'm not fluent, so I might not explain some things perfectly but I will try to get it clear. My friend's dog, who is almost a 4 y.o. Aussie Shepherd, sometimes has unexptecting incontinence (it started the last summer) without any visual reason. His owner does frequent check-ups and the dog has almost perfect analysis. The dog is given some hormone pills because of the kidneys disease (he was deprivated with water when he was a puppy, so he got some troubles with it), he has balanced natural diet and goes out 3-4 times a day without big time distances between walks (less than 6 hours). He is not castrated and hasn't been bred yet. There were several suggestions why it happens: 1. Because of the emotional overwhelmment 2. Because of the hormonal medication 3. Because of the kidney disease Let's start with first. The dog is really emotional, but the problem is that incontinence isn't regular. If the reason of incontinence was his emotionality, then he would wet every time he gets emotionally overwhelmed. The second. He used to take some Russian substitute called 'Euthyrox' and now he takes original 'L-thyroxine 50' once a day for already 4 months. The third. His kidneys are not that bad and his bladder is either okay. They are going to go check up soon, so they will take some urine tests. Additionally, he might urinate unexpectedly because of the cold, but he actually did it while it was 30 degrees outside. He drinks a lot at days he wets, but he has anytime availability to water and strict food schedule. I would be grateful if you made some suggestions about the reason of this, because our vets can't do anything about it... Thank you ❤️

Sorry, I was a little bit mistaken. He takes his hormonal drugs because of the thyroid gland troubles, not kidneys

What I love about this post (as well as the heart emoji) is the way that you considered possible reasons and explained why you have ruled them out.  This showed that you were trying to follow a logical diagnostic process exactly such as a vet ought to, which makes me very happy.   It also makes it easier to perceive possible gaps, so here we are.... Medication - side effects are easily ruled out by looking at the data-sheet, the sheet of dense text provided with the tablet bottle.  In the uk this is a legal requirement for licensed medication. I beleive that Levothyroxine overdose can occasionally cause Polyuria and Polydipdia as well as potential hyperactivity.  Sometimes this is to do with the dogs' individual requirement, other times accidental double dosing, which would explain the intermittent nature.  I do not know enough about the other drugs- being open with the vet may help. Worsening kidney disease, diabetes, liver disease, Addisons, neoplasia, parathyroid disease and so on can all cause an excess in drinking therefore urinating, so may need to be ruled out.  Your vet can do this with an appropriate urine stick test and by checking the specific gravity of the urine.  These results do change quickly.  It is not unusual to encounter other illnesses alongside thyroid disease Cold - I have never heard of this, although a dog might be less keen to toilet outside in cold weather Emotion is never simple or logical - 'if it happened with emotion it would happen every time the dog is excited' is not logical to me.  I do not cry every time I am sad, for example.  Perhaps sometimes when he is excited his bladder is empty, or there is something else over-riding the impulse to urinate. Lumps, bumps and crystals in the urinary system may also be possibilities. dietary changes - 'natural' is not always the same as 'appropriate.'  Please ask your vet to check through the dietary constituents to check, for example, the Potassium balance. I hope that something here gives you some ideas.  I know that you have already consented to the site rules which will discuss confidentiality,  but I should reiterate that if by any chance this is posted without the owners permission, even though it appears quite safely anonomous, please remove it. Please also note that the vet may have ruled a lot in or out already; it is perfectly ok for the owners to ask them the 'differentials' (possibities) list and what has been ruled in or out.  As ever, the vets are the best people to offer advice in this case and should refer any case with which they are unableto make progress. PUPD - drinking a lot and urinating a lot - is seldom trivial and should be taken seriously.  There are guidelines as to how much 'too much' is- the vet will help them to decide. I hope that something there helps.  

My apologies, polyuria and polydipsia is the medical term for drinking and urinating excessively.   The specific gravity of urine, a reading that your vet takes from a urine sample, can help to identify types of reasons for this.

Sometimes on clinical notes they are abbreviated to PUPD
