hi ive just bought a saint bernard puppy ive been told by the breeder to give her the green tripe ,also the sheperdess milk ,n drinking water and also a calcium tablet half a day . can she have a handfull of mixer or complete food in this ? thanks

Your best source of information on feeding your pup is her breeder who should be happy to clarify any instructions given.

I don't think feeding such a fast growing large breed on green tripe alone is a very well balanced diet - but I'm not a Saint owner. Have a look here
