Hi there... I have a 10 month old Boxer girl. She is 45 lbs (is that small?). I have been feeding her Eukanuba Large Breed Puppy food since we got her. I have been reading all of the bad posts about Eukanuba and just bought my first bag of Canadae yesterday. I had to order so it is not in yet... First I wanted to ask if I have done her harm by feeding her puppy food this long? She seems very healthy and active (despite pneumonia at 6 months). She has had some localized d-mange and now has a wart near her eye (was hoping maybe the Canadae would help her skin some?) but otherwise is very typical Boxer puppy. My other question was how to begin the new food. I have some Eukanuba left... Should I go 50/50 for awhile? Should the guidelines on the Canadae bag be followed to the letter regarding portion size (seems small...)? Thank you so much for any input!
