My 12 yr old pug has early stage kidney disease my vet believes still waiting on tests.he just gave me a supplement for arthritis called phycox Ha. It has creatine monohydrate 90 mg in it.i know with kidney disease it is bad to have high creatinine levels in their blood.will this supplement with creatine raise her levels of creatinine which would make her kidneys work harder and be bad for her.im nor sure and will have to ask the vet but need someone to help now.thanks
