coat

i have heard of some ways to keep a good coat for your dog. i know a teaspoon of olive oil helpls get rid of dandruf. but i have heard eggs keep a shiny smooth coat. if this is true do i give raw eggs or cooked. i take pride in my dogs coat i just want to know ways i can keep it nice.

Okay, I have a year old red nose and her coat is super short and kind of corse, well we just got an 8wk old male and his coat is nothing like hers, his is short but its really soft and kind of fluffy, is this normal or is he possibly mixed? I have been googling pictures trying to see if I can...

My pit is 6 months old and his coat is more or less dry and not shiny or smooth. i've been feeding him pedigree dry food. im not sure what kind of food he shoud eat to get his coat back to shiny and smooth. any advice would be helpful, thank you!!
