Hi annclare, so sorry I haven't got back to you before. I'm sorry to hear Nina has Cushings, I hope she's doing well on the medication. Over 20 yrs ago we had a cocker with it and he did well on the tablets and lived to a good age, despite putting on lots of weight. It was a nosebleed that caused him to be pts in the end, the vet thought he had a polyp in his nose and it started to bleed and there was no way of stopping it unfortunately.
We have to take Hugo fortnightly to the vets to check his ears, he has yeast growth and every visit she weighs him and he's put a little bit more weight on each time but, she's not concerned, its the downside of steroids.
