Dog nutrition is one of my favorite topics so prepare yourself for a reply that'll probably be more like a book! LOL
As others have noted, the Angel Eyes contains tylosin which is an antibiotic. Long-term use of an antibiotic for cosmetic reasons is not something that is usually recommended by vets.
I've got some concerns about the Pet Kelp product. People tend to think of kelp as some kind of miracle food because it is usually advertised as containing a multitude of vitamins and minerals. This is true but what they don't tell you is that the amount of most of them is so miniscule as to be insignificant. The one mineral it usually contains a large amount of is iodine. Too much iodine can interfere with the proper functioning of the thyroid.
Your 5 lb adult dog requires 54.79 mcg of iodine per day. Half a cup of Orijen contains 108 mcg. This is about twice what she needs, but isn't a problem. The amount of iodine in a commercial pet food will have been calculated to take into account any other ingredients in the product that might bind with the iodine and ensure there's enough left over for the dog.
The Pet Kelp contains 311 mcg per 1/4 tsp which is the amount of the supplement recommended for your dog. This is about 6 times what she needs. Neither blueberries nor flax (the other ingredients) are going to bind any of this iodine so it will all be available to your dog. I'm not a veterinary nutritionist so I can't tell you if long-term supplementation with a product that contains 6 times the iodine she needs will cause any thyroid problems, but, personally, it's not something I'd feed.
The amounts of the other minerals and vitamins in this supplement are teeny, tiny and really don't add anything to your dog's nutrition. A good commercial food like the Orijen contains all the vitamins and minerals your dog requires so there isn't any need to supplement these.
The Pet Kelp also contains flax seed which is used as a fatty acid supplement (primarily for omega 3). I've never seen the product so I don't know if the flax seed is whole or ground. If it is whole, it'll basically just pass right through, it'll provide some fiber but your dog won't get any of the benefits of the fatty acids. In fact, even if it is ground, flax seed contains ALA, a type of omega 3 that comes from plant sources and is not easily processed by dogs. Dogs do best with EPA/DHA which are omega 3 fatty acids that come from animal sources.
The blueberries in this supplement do contain important antioxidants but there is no reason you cannot feed your dog small amounts of fresh fruits and vegetables to achieve the same end.
Which brings me to Dr. Maggie's Skin and Coat supplement. It took a lot of digging but I finally found that the source of the omega 3 in this supplement is soy oil. This is ALA and not a high quality source of omega 3. Soy oil also contains omega 6 but dogs rarely need extra omega 6. It is a common fatty acid found in meats. The site also says the product contains omega 9 fatty acids. Omega 9 is not an essential fatty acid for dogs so no need to waste your money supplying it. If you feel your dog does need some type of fatty acid supplementation, you could add a small bit of some type of fish body oil (not fish liver oil).
I realize I have just panned every supplement you've bought but it is not my intention to criticize your choices. I know you only want the best for your new dog. My intent was to provide information and basically to let you know you can save your money and Eden will be just fine.
