Thanks Jay. How do you use the Vitamin C solution? Do you put it in the water bowel, or brush the teeth with it? Eli ALWAYS knows if I added something to the water bowel, and just won't drink from it until the substance is removed. I do give bones now and then. It's a bit of a production, as E and his sister Dixie both have a bit of food agression when it comes to something special like a bone. I also use Twistix, Texas toothpicks, munchy stix, dried sweet potato(they don't like that much), and, most recently, dried chicken feet. They look gross, but are all natural and made in the USA. Salmon skin rolls are also a favorite. I will try the bones again this weekend. I would like to do the dental cleaning, but don't want to do the echocardiogram. The vet is perplexed by this. E is doing so well, I just don't want to know if something is wrong.
