hey hey hey.......... sidhu dont talk about 50-60 year old time, at that time a amn can eat too much desi ghee per day may b near about 1/2 to 1 kg per day. but now a person cant even eat 50gm desi ghee, if he eat with in few month he will face problem of blood pressure, heart attack........ time has change...... im agree few year back milk egg roti meat are teh main diet of dog, but time has change......... we have to change with time, i know milk has many ingredients good for health but u know recents research told that its very difficult for body to digest. left is your choice.
if u talk about taste, i think ur children at home also like to eat sweets, toffies, chocolate, than why we give them in limit, becoz they have side effect, same thing happen with dogs, for dog they have more sideeffect.
one more thing chocolate is liked by every person, even can can eat it in second they alos like it, i just say u feed 1 chocolate to your dog for 1 week, than find the result. with in one week your dog either die or will reach in condition to die. u tell other to do google, first u urself do google for feeding sugar to dog. than tell to other.
if you like to take care of taste of your dog u can give him other tasty things like meat, egg, curd etc.
left is your thinking choice
