Thought I would claim for Daisy's medication since she was diagnosed last August as I haven't so far, so I have been rereading all her notes from my vets and also Chestergates and North West Surgeons .

Upon reading my vets "Client Record" there is " Furosemide 10 mg daily ONGOING to control cerebrospinal fluid pressure and prevent dz progression .Adv check serum K+ every 3 months " but as she was then also diagnosed with a Grade 2 murmur which resulted in my dropping furosemide and putting her on Cimetidene (advised in an earlier thread my reasons for this action )do I get the serum checked or not now ,also can somebody please advise what serum K+ is and what its for ,also what does dz mean ?
