people used garlic in dog food flavoring for years. Some dogs seem to be able to handle it better than others. Some people even use it for coat conditioning and insect repellent.

Tag is not into the real stuff yet, I am weaning him off of icky science diet that the Humane society was feeding him. I would never feed hot dogs to dogs. They do have garlic AND onion as part of their spices, not to mention too much salt.

On the other hand, Foxxy gets fed kelp and spirulina daily. She loves the stuff and actually begs for it. I cook with seaweed all the time, either kombu, nori, or wakame. Turns out that these plants are super rich in vitamins and minerals including iodine and magnesium to support tiny thyroids and joints. The spirulina I stumbled across after spilling my plecostimus's tabs knocking them off the fishtank. Foxxy was right there to hoover them up too. (crunch crunch crunch) I researched to make sure they were ok and sure enough they're a superfood as well.
