Charley started on Vivitonin on Tuesday evening after we returned from the vet's. He seems a little improved, and wasn't pacing up and down the lounge as he usually does.
Interestingly, the information given with Vivitonin states that it increases the blood flow to the heart and skeletal muscle as well as to the brain. It also reduces peripheral vascular resistance thus lowering cardiac load. It also suggests that there should be a rationalisation of medicine for dogs already receiving treatment for congestive heart failure.
It is early days yet, but it would seem that Vivitonin will also treat his underlying heart problem.
