I started ridiculously low, because he's never had it before, and there's always the possibility of a reaction.
I'm pretty sure that I'll go up to 3 or 4 drops, if this is the full improvement. But, I'd like to stay at the lowest dose possible, that works for him.
If he ended up at 4 drops, say, then that would be 1/3 of a 'normal' dose for his weight. But, we'll have to wait and see.
It's hard for me to believe that he's 15, too.
I hope that ending up in the creek (*shudder*), especially when it was in the 20's out, has taught Uhura a lesson, too.
The feeling that you have about Sophie not being dx'd earlier, is the same one that I have about Jet not having been dx'd with his Cushings earlier.
And, like me, you even asked questions that weren't correctly answered. It was the vet/s that dropped the ball on both dogs' problems.
The way that I finally came to see it, is that he did well on his medication, and improved greatly. I feel very sorry for the time that the vets' wouldn't listen or treat him, but the rest of his life, once treated, was improved immensely. He enjoyed his life then, as the quality had improved so much.
I think that the story is the same for Sophie. She did have the problem, but you finally found the right vet to dx and treat her. And, now that she's being treated, her health and quality of life are *so* much better.
Looking back just doesn't help, once a problem has been solved. Just look into her eyes, and know that she feels better now, and has for a while now already. It's the best that any of us can do, without a time machine.
There's nothing like a good vet or human Dr. to make life easier, and more pleasant, is there? I'm glad that you've found the one that you have!
