Liz S, I also think adding canned will do much, much good! When I use canned, I prefer the pate-style ones, and I add a bit of water with the canned and kibble (I mix dry and canned usually), and make it mushy/porridge-like/soupy, and this way I try to counter the dryness of the kibble.
My dog is small too (Jack Russell-mini Rat Terrier mix (we think, as he was found in the bushes), 13.5 lbs), but I never really fed him a small-breed specific food except for his very first one when we adopted him. Foods I have tried that he did good on (and could eat the kibble with no problems) are: Blue Buffalo Wilderness, Vets Choice Holistic Health Extension, Dr. Tim’s (slightly bigger kibble, but oh well, he managed it just fine), Nutrisca, Earthborn Holistic Grain Free, Victor Grain Free (lots of samples), Nature’s Variety Instinct (samples), Now! Fresh (sample), NutriSource Grain Free (samples), Annamaet (samples), Wysong (samples), and I have a lot lined up – Back to Basics, Canidae Pure, Dogswell LiveFree, Wysong, NVI, more Victor Grain Free (which, in my case (heads up to LabsRawesome), told me I could PURCHASE the samples at $0.33/baggie, but wouldn’t send me free ones, AND I had to pay the shipping… But I stocked up at 5 samples/food, lol).
All the kibbles aside from Dr. Tim’s were small enough and just fine to manage. For canned I have fed Wellness Core, Nutro Natural Source and Nutro Ultra, and now I feed The Honest Kitchen (THK) dehydrated with water instead of canned. I also add a raw egg once a week, coconut oil with some lukewarm water every other day, and yoghurt/kefir every other day, as well as a canned sardine and its fish juice from the can once a week too. So you can use some of these for variety and to cut the costs of canned.
