They make a canine redcell for dogs. Should be able to buy at local feedstore.
I give my bulldogs 5cc once every other day over their food along with 1 oz of Liquid Dyne.
Keeps them in top condition.
i dont give it to my hog dogs unless they get a lil thinner than i prefer but i raise apbt and on them i do the same thing as above but give 8 cc of red cell everyday into their mouth and 10 cc of dyne every other day but it will get em fat quick like that i just kinda played with until i found a dose i liked you will def know when your giving to much they will start scourin
