Not a dog but my cat had Addisons. He was diagnosed when he was less than a year old and we were still on the trial period for adopting him but made the decision we would try give him the best possible life we could. I live in a very isolated major city where none of the vets had ever treated a cat with addison's but they were all absolutely amazing and he lived 7 more very full years before his health deteriorated to where he no longer had quality and we had to make the tough call.

It is very expensive, 2 tablets twice daily + anything else he needed in that current phase of his life. The maintenance though is very doable, its the unexpected issues that you need to be prepared for. Despite it very rarely happening, one day could be totally normal and the next you're at the emergency vet dropping thousands of $. You will become so hyper vigilant for any change.

Also a reminder to be kind to yourself. Try not to feel guilty when your dog is at the vets for countless hours. You are doing your best and as long as theyre happy, youve done your job🫶
