The whole idea with the danger of various protein sources is that there is not really that they will develop a food allergy, it has to do more with the availbility of these protein sources.
Currently, the vast population of dogs feed on foods that are mainly chicken, and beef product (and recently lamb). Many times, the food allergies that dogs have involve the protein source, which is why foods like IVD have diets like rabbit, duck, venison. They are not "allergy diets" per se, but instead have ingredients that from different sources than normal dog foods.
Now is feeding your dog food that has fish, or duck in it bad for them? No, not really, in fact it's quite nice to have a variety of protein sources in the diet. Mandy is right, it does increase the possibility of a food allergy, but you will know if it does cause one.
Why is feeding your dog a variety of protein sources bad? It's not really bad for your dog if they aren't allergic, in fact it may be good. But it's bad in the long run for other dogs. The only reason (I've asked a dozen vet nutritionists this question) is that there is only so much availability of protein sources out there, with chicken, beef, and lamb being the most available. If dogs without allergies consume all the other protein sources like duck, rabbit, and venison, there may not be much supply left to feed those with allergies. In addition, if dogs are exposed to all of these protein sources and become allergic by continued exposure, what protein source will be left to feed these dogs? We'll have to start looking elsewhere for meat like Kangaroo, horse, pork, etc...
Hopefully that makes a little sense. This is why many of the alternative protein foods are prescription only, to make sure that the protein sources are not wasted on dogs without allergy.
I think that a little fish mixed in with the other protein sources can be a great addition to the diet since Omega-3's are key, but I wouldn't switch them to an all duck or rabbit diet just for the heck of it.
If you have any other questions, ask your vet about it or I can try to answer them.
