My Sooki is 11 years old and weighs 19 lbs. He was diagnosed with a heart murmur and congestive heart failure and after an arguement with my vet about them doing blood test and xrays on Sooki without my permission they only charged me for the office visit and woud not sell me the medicine they were going to give him. I read online to give him Furosemide and Enalapril but am not sure what dosage and frequency of giving the medication. I am out of work and don't have the money to go to another vet. Anyone that can help would be greatly appreciated. Thank you!!!
