cod liver oil is a no no no?

[keanna_my_tzu]

i've read somewhere here na bad daw yung cod liver oil sa tzu?how true?
i am giving my baby that for since i had her pa naman!
please, please educate me...
ang sabi kase nila pampaganda daw ng fur yun!actually right now may sugat siya, although hindi naman ganun kalaki like the first time na nagkasugat siya pero madalas siya magkaroon ng sugat and right now malapit na matuyo. sana lang di na siya ulit magkasugat!...and may balakubak pa (oh God!)...
i am using sulfur soap para sa sugat niya. then i would use betadine and pinicilin. after a week wala na pero bumabalik eh...is it due to summer? i am planning to get her to a vet next week!(financial matters kaya next week pa.)
i read na mali pala ang way ko ng pagpapaligo kaya naman siya binalakubak...
so sinusunod ko na ngayon yun nabasa ko... di ko pa alam kun mawawala ang balakubak niya...once ko pa lang siya napaliguan the right way!huhuhuhu! i am a bad owner pero i am willing to make it up! yun ang importante right? ang willing ka to make it up!and admit your mistakes din!

please advice...regarding the cod liver oil! at kung may alternative!if you want you can also comment about her sugat and balakubak!i really need suggerstions right now!
