Rusty looks adorable!! Congratulations
I find that a baby finger toothbrush works best for my furbabies. I like to use Petzlife oral gel which you can buy online. I think there are a couple of members who carry it on their websites.
As far as brushes go, a good pin brush WITHOUT the little balls on the end. The little balls on the end break the hair. We use Chris Christensen's gold series pin brush. Look on Petedge...There are other brands on there too. or a Boar bristle brush I have heard is good also. Mason-Pierson is the one that I hear recommended most of the time, but it is very, very expensive.
Eukanuba is not a good food in my opinion...Check out
www.dogfoodanalysis.com and look at the 4 and 5 star foods. Canidae is a good one (
www.canidae.com), Innova, Solid Gold, etc.
