Although I am new to owning a cavalier, I did a lot of research prior to picking up Leo.
So, here are the questions (Sorry this is so long!). I have been feeding Leo Authority puppy chow, which is a pretty decent food. However, having seen what Karlin has said on this site, I think it might be best to switch to Canidae All Life Stages because I don't want to contribute to hip dysplasia in a breed that's known for it. The only reason I haven't switched yet is because Leo looks very skinny to me. When I take him back home to play with his brothers and sisters, they are much pudgier and baby-like, whereas Leo (at over 9 weeks old) already has an hour glass figure and weighs about 3 lbs. All of his brothers except for the runt are bigger than he is, but they ARE free-feeders, which I've also read is a no-no.
Leo DOES eat--however, I am following the advice of Dr. Ian Dunbar religiously, so we have been using his food to train him. He is a very happy little puppy, and he loves nothing more than showing us he can sit, beg, lie down, (almost) roll over, and he knows "off" and "take it." With that said, however, I'm concerned as to whether it will be harder to get him to eat at mealtimes. He already won't eat out of his food bowl because of an unfortunate accident he had when we first got him where he overturned the food bowl onto himself.
Sorry this is so long. I have more questions, but I think I'll wait and make another post later because this is already pretty unwieldy.
