Health problems.

WE DO NEED A QUICK ANSWER, BUT IN CASE DOG WILL HANG ON, HERE GOES: 10 YRS OLD FEMALE DOG, BELOVED PET, HAS SOME SORT OF KIDNEY PROBLEM: IS WETTING ALL THE TIME. ALSO SOME SORT OF HEART PROBLEM MAYBE ARITHMIA, AND WHEN THE DOG IS SLEEPING HER BREATHING IS SEEMINGLY JUST FINE. WHEN THE DOG IS AWAKE, HER BREATHING IS VERY LABORED, AND YOU CAN HEAR THE STRUGGLE. SHE SQUINTS HER EYES LOOKING LIKE IT'S DUE TO PAIN AS SHE BREATHES.
A VET HAS NOT GIVEN A DIAGNOSES, I DON'T THINK HE KNOWS, HOWEVER, HE HAS GIVEN HER SOME PILLS THAT SHE STARTED, AND MUST BE WEANED OFF OF. WHAT IS YOUR THOUGHTS ON ALL THE SYMPTOMS. DOES IT SPARK A MAIN CAUSE FOR THIS SERIOUS SITUATION. MY BROTHER FEARS SHE WILL SOON DIE. THIS WILL BE VERY DEVASTATING. MY BROTHER HAS LIVED WITH NO ONE FOR THE ENTIRE TIME HE'S HAD THE DOG, AND SHE IS LIKE HIS CHILD ! ! !
ANY SUGGESTIONS WILL HUGELY BE APPRECIATED ! ! !
THANK YOU VERY MUCH .
DUE TO CUT-BACKS WHERE I WORKED, I AM UNEMPLOYED, OTHERWISE, I WOULD PAY YOU FOR ANY HELP YOU COULD OFFER. THEREFORE, I HAVE TO GO THE FREE, 4-7DAY ROUTE, AND HOPE HIS DOG, MOUSE, WILL HANG ON. GOD BLESS.
