This is what my dog training colleagues in Sweden said about Eukanuba:
"Ann-Marie Hammarlund (one of the most famous vet in Sweden) doesn't want to take a stance against any pet food, with one exception - Eukanuba. She warns that 95% of the owners contacting the clinic regarding food related issues, fed their dogs Eukanuba.
So what is wrong with Eukanuba?
* Not enough fibre - the intestine doesn't get enough work. Many older Eukanuba dogs have disfunctionate intestines.
* Too concentrated - small amounts of the feed leaves a lot of dogs with a constant hunger. I've also heard of dog owners that have given as much E to their dogs as they used to give of the food they used to use without the dogs putting on weight (although I will confess that I've never put any more thought into why that would be).
* Too high energy tightness - most family pets get more energy than they can spend and that leaves them stressed and frustrated.
* Is likely to contain growth hormones - I've seen so many 3 month old bitch puppies with early seasons and problems in that area, plus over sexual behaviour in male dogs. This was around the time that the E food was at the top of the Swedish dog food market. The E feed is tested, but the Swedish laboratory could not prove that it contained growth hormones (but they also say they can't find ca 40% of the known performance enhancing drugs used within different sports, due to the lack of resources). In the US it is accepted to feed chickens with growth hormone and then use the chickens for human food. While I was on the war path against Eukanuba I read about a female doctor in a poor country (can't remember which one now... maybe Puerto Rico?) that started investigating why small girls of 3-4 years old got pubic hair and menstruated at such an early age, in large quantities. The common denominator proved to be that the poor population almost exclusively fed on leftovers from the nearby chicken factory!
* Addictive - It is known that food manufacturers used to use Belladonna in cat food, to make the cats want this food and nothing else. Personally I think they do the same thing with dog food. A breeder that I know had two feeds that she would use for her dogs - Eukanuba and Hills. I had been trying to get her to stop using the E, but she wouldn't. She switches between the two feeds for both her adult dogs and the puppies. Last summer she had a litter of puppies that I met when they were 7-9 weeks old. Towards the end of my first week there, I was watching 4 of the male puppies working hard to mate each other and any available pillows (these puppies were not of a breed that is known for high hormone levels). I asked my friend which feed they were getting at that stage and she said they had had E for the passed 2-3 days. I convinced her to switch to Hills instantly, to see if the intense mating behaviour would disappear. From the day after and for the following 10 days that I was staying with them, there were no more attempts at mating each other or the pillows.

That was what I've read by my colleagues so far... I'll let you know if there is more!
Not only are Eukanuba/Iams food that can make your dog over sexed and hyperactive, they also do animal tests and treat the laboratory animals in the most appalling way. If you give your pet Iams or Eukanuba, I challenge you to watch the PETA video (link below) from one of the Iams/Eukanuba labs. The images are horrid and if you are brave enough to watch it, I bet you will make damn sure that the food your pet is on isn't tested on animals. WARNING! These images are very unpleasant. http://www.petatv.com/tvpopup/Prefs.asp?video=iams
