The dog recovered again and the owner decided on a wait and see approach for now. if it happens again maybe I can convince him into further investigation or trial suprelorin (I think he does not want to castrate him really). If it is traumatic, perhaps a neighbour had a bitch in heat!

I tend just to advise castration unless there is a good reason not too, to me it is the treatment of choice and a permanent solution. Ypozane works for sure, but is expensive

I would want to know if the prostate gland is enlarged first, and given the dog wouldn't tolerate a rectal examination sedation may be needed.

If smooth and symmetrically enlarged, and assuming it's benign prostatic hyperplasia (most, >95%, likely to be), I would advise castration, so could all be done under one sedation/GA?

If one, or the client, wanted a definitive diagnosis then one would have to go down the route of imaging +/- biopsy +/- prostatic washes +/- prostate specific blood test etc. Every case I can think of where a full investiagtion has been carried out, have gone round full circle and ended up being castrated or have Ypozane.

haematology and clotting studies normal, so a systemic coagulopathy very unlikely.

Hi,

Thanks for the interesting case. These lesions really do look like petechiae and ecchymoses so I would still be concerned about a clotting disorder and looking again at platelet numbers especially, bearing in mind you could be dealing with a thrombocytopathia, not necessarily just a thrombocytopenia.

Has the dog ever travelled abroad? Is it worth testing for lungworm, anaplasma, rickettsia etc?

Imaging would also be a good shout as there’s a chance neoplasia could be triggering something.

Hope you get to the bottom of it!

I had something similar a while ago in an entire Bully. Was causing penile trauma from aggressive humping etc. Owner refused to acknowledge that was the case.

It could lead to a urethral prolapse so worth monitoring closely, and trial suprelorin.

Urinalysis? any blood in urine ?

Seems traumatic is my first thought.

Prostate and bladder US scan may be helpful.

If unsure about castration, could try Suprelorin, although expensive and may cost (almost) as much as castration.
