Hi! Your pup is very pretty! Two UTI's aren't a good sign, however. It's also excellent that you know that giant breed pups shouldn't be fed puppy food, in fact, they shouldn't be fed any food with protein levels over 24%.
Also, you might want to try finding a different vet who knows about giant breeds as they come with their own set of health problems. Since the big fear in owning a great dane (for most people) is bloat, you should definately find out if your vet is equipped to handle a case of bloat and possibly torsion. This is where the stomach swells with gas and can actually twist, a situation that can kill your dog in a few hours. Emergency surgery can sometimes fix this though. You might do more research if you aren't familiar with bloat as it is a huge problem (even worse is the lack of information about what causes it).
Your breeder doesn't seem like he/she would be much help b/c your pup's parents should not have been bred. According to the Great Dane Club of America's Color Code, Fawn danes should only be bred with fawns or brindles, harlequins should be bred with harlequins or mantles, and blacks should be bred with blacks/blues. (You can check the color code at www.gdca.org).
I hope this helps you. You have a beautiful girl, I hope you two have many years of happiness together.
P.S. I almost forgot www.danesonline.com is a great board for information regarding danes, there are many reputable breeders with many years of experience on that board and a ton of information for new dane owners!
