Our dog Pierre (min-Poodle mutt, approx. 20 lbs.) is 11-ish (not sure b/c he's a rescue). About a year ago our vet suggested that he may have Cushings but at the time we were advised the tests for diagnosis would run almost $1K and we had just been through an expensive medical episode. Also he did not show any adverse symptoms at the time except a slight increase in water intake and appetite.

1 year later, he had a very bad week; ended up at the specialty hospital where they found an infected abcess in the liver, recommended surgery that would have been upwards of $6K. We promised ourselves we would not go into a cycle of endless debt to prolong our dog's life in the later years. We were given the option of treating the infection with antibiotics, which seems to have worked well.

Our vet and our specialist have been very attentive and after a few follow-up ultrasounds the specialist cannot detect any sign of the infection; however he recommended we continue Clavamox (antibiotic) for another 6-8 weeks until the next ultrasound.

Meanwhile, we have been treating the enlarged gall bladder with Ursodiol since a few weeks after we started antibiotics, and it seems to be effective.

About two months ago, when signs of infection were gone, we started Vetoryl @ 10mg per dose, twice daily. No bad side effects but no effect on his water intake and output after a few weeks, and another ACTH stim test indicated his cortisol levels were still at 20 or so (not sure what that measurement is exactly). The specialist said he wants to see that number around 4.

Bumped up the dosage to 20mg x 2 daily. Next ACTH test pegged at 12. Specialist recommended 30mg x 2 daily. After a week of that still no change in water intake/output, so (with advice of specialist) we bumped up the dosage to 40mg x 2 daily.

Pierre has not displayed any significant side effects from the Vetoryl -- no diarrhea, vomiting, etc. He's a bit lethargic but still up for playing a bit. He's weaker since this whole thing began but he has also gone from 26 lbs. to 17 lbs. -- he was always considered overweight and now we are trying to fatten him up. Since he still has increased appetite, he will eat all that we feed him.

After two days of the 40mg x 2 daily Vetoryl the incontinence and/or inappropriate urination has only gotten worse. We are using diapers/wraps but even these do not stem the tide of urine flowing onto our floors, furniture, bed, etc. This happens sometimes within minutes after taking him out for a (productive) potty trip. Patience is running thin and I'm afraid Pierre is picking up on it which may be exacerbating the problem.

Specialist recommended considering an incontinence drug but we (and our primary care vet) are reluctant to add another drug to the mix.

Any advice / shared experience / recommendations appreciated from folks who have had similar circumstances...

I would recommend the vet look into DI - Diabetes Insipidus. It is a rare form of diabetes that does not involve blood sugars but rather how the body processes water. The test, a water deprivation test, is risky so most vets will simply start treatment (treatment is an eyedrop) and if that helps the issues, there is the diagnosis.

The dose of Vetoryl your baby is on is MASSIVE and would frighten me but you say he isn't showing signs of an overdose so I will try to breath a bit easier. ;) We use Lysodren so I will let those who use Vetoryl (Trilostane) speak with you about this.

Hi And welcome to the forum. I just wanted to say please test for what Leslie told you. Your dog for it's weight is on way to much Vetoryl and could have an addisons' episode. That is an extreme amount for a dog of that weight and , and there is something else going on. Dechra recommends 1mg per pound. Please call Dechra and start a file on your dog. They have vets there and techs that can help and guide you through this 866-933-2472. Please do not continue with this high dosage and call Dechra. They will help you and your vet, he can call them too. Blessings

Thank you for the replies. I agree that the dose of vetoryl seems high based on Dechra's guidelines. I was glad that the specialist started with low doses and gradually increased.

I am going to bring up the diabetes insipidus idea with both vets, after reading about it it does seem like Pierre is presenting classic symptoms of DI.

I will post back when we find something. Thank you so much for your recommendations!

Hi and welcome to you and Pierre.

Diabetes Insipidus is very rare and I personally would not suspect that's what you are dealing with. With so little information about why Pierre was diagnosed with cushing's, we can't really provide much meaningful feedback. Can you please tell us what symptoms associated with cushing's did Pierre have that made your vet suspect he had cushing's. What tests were done to confirm the diagnosis and were those tests done after the gall bladder and liver issues were resolved? Was Pierre diagnosed with pituitary dependent cushing's or an adrenal tumor? I see that he has had more than one ultrasound. Can you please tell us if the radiologist provided information on the adrenal glands and if so, what were his/her comments about them? Aside from the abscess on the liver, was there any mention of steroid hepatopathy consistent with hyperadernocorticism? Can you please get copies of all tests that were done to diagnose Pierre and post those results here. We would be most interested in acth stimulation test, low dose dexamethasone test.

UC Davis has vast experience with Vetoryl (Trilostane) and their studies reveal that there are a small percentage of dogs who never see resolution of pu/pd with treatment. We've had at least one member who felt her dog never had cushing's because her dog was asymptomatic. Despite no symptoms, which are a huge component of confirming a diagnosis, her vet prescribed Trilostane and shortly after treatment her dog started drinking and peeing buckets. She discontinued treatment and the problem went away. I'm not saying this is what is going on with Pierre but it's possible. If Pierre doesn't have diabetes mellitus or any other concurrent condition that is worsened or difficult to control in the face of high circulating cortisol, you could test the theory by discontinuing Vetoryl to see if Pierre improves.

I'll be looking forward to a lot more information about your boy and his diagnosis.

P.S. Is the specialist a board certified internal medicine specialist?

Hi lulusmom,

Pierre did present pu/pd for several months, as well as bloated belly and greatly increased appetite, before we had the crisis with the liver infection. At that time an ultrasound was done, which discovered the liver abscess, inflamed gall bladder, and enlarged adrenal gland.

We were told there was no sign of kidney disease or diabetes and all other blood work looked good.

After starting him on antibiotics (Clavamox and Baytril), we went for a second ultrasound a few weeks later and the abscess/infection was very much reduced. Started him on Ursodiol for the gall bladder issue at that point.

Next ultrasound a few weeks later found no signs of the liver infection. At that point we got an ACTH stim test for a baseline -- they said his cortisol levels were extremely high. Started him on Vetoryl at 10mg twice daily.

2 weeks later another ACTH stim test showed cortisol reduced -- I do not have the exact test results but the number our main vet and the board-certified internal medicine specialist are looking at went down to 20. Specialist said he wants to see that number at 4 or so.

By this time we had stopped the Baytril; another ultrasound showed great improvement in the gall bladder. Also he is visibly not bloated in the belly anymore. However, he has lost too much weight and his pu/pd has increased if anything. We continued Clavamox, Ursodiol, and bumped up the Vetoryl to 20mg twice daily (total 40mg per day).

Two weeks later another ACTH stim test showed "the number" at 12 -- all symptoms pretty much the same. Specialist told us to go to 30mg twice daily. A week later, after pu/pd seems to be getting worse, specialist told us to go to 40mg twice daily and we have another ACTH stim test scheduled for 12/30.

I will try to get the full test details, and also call Dechra as recommended. Other than the pu/pd, Pierre seems relatively happy but I know it's difficult to really know when a dog is in pain if the pain is mild to moderate. I should also mention that once the liver abscess crisis was addressed, it wasn't until a few weeks later that he became much weaker/wobbly in the hindquarters, unable to jump up to furniture or into the car as he used to -- though we have found that he sometimes achieves that when we've left him at the house alone for a while (he's never left alone for more than 2 hours at this point).

His appetite has never really abated except for the week of the liver abscess discovery which started us down this path. Even then he only refused food in the evenings until we started the antibiotics and then he was pretty much back to insatiable.

Thank you for the detailed response and I'll get back when we have more info.
