Christina, I would say probably give it a few days (2-3-ish) before you add a new ingredient just so you know if he would react for sure. As for tomatoes, I guess you could put them in a blender or food processor for a few seconds until they are pretty much mush, then try them. Make sure the whole elimination diet does not last too too long, as it is not a balanced way to feed a dog, so hopefully within 10-14 days you will know if he reacts to a particular ingredient. If he doesn’t react to any of the ones listed above, I would go with a grain-free diet, or a rice-and-maybe-oatmeal-or-millet-or-barley-as-the-only-grains diet. But grain-free is generally safer for an allergy-prone dog.
One of my classmates and friends told me that her dog was extremely itchy eating Pedigree and Beneful, so I told her what I know, and she got him on a grain-free diet – said the itch has been considerably reduced to just an occasional “normal” scratch here and there. She didn’t do an elimination diet, just straight up eliminated the grains, and she was lucky her dog did not react to anything else. So that is also another way you can approach it – just try a good quality fish-based kibble and add the THK Beams as treats and coconut oil, and see how that goes. I would probably still do an elimination though, just to be sure for myself. But, it may work out that he just needs good-quality grain-free kibble.
In case you want to just try the kibble round, some good grain-free kibbles (I will just list them for your ease, in no particular order) are:
Wellness Core – I want to feed in the future
Holistic Select
Orijen – I want to feed in the future
Acana Grain Free – I want to feed in the future
Victor Grain Free – I feed now
Earthborn Holistic Grain Free – I feed now
Dr. Tim’s Kinesis Grain Free – I have fed, no issues
Holistic Health Extension Grain Free – I have fed with no issues and I feed one of their grain-inclusive formulas now
Now! Fresh – I have fed a small bag (less than 1lb) with no issues
Nutrisca – I have fed, no issues
Nature’s Variety Instinct – I will feed (have a bag lined up under the sink, lol), and I have fed samples with no issues
Back to Basics Grain Free – I will feed the grain-inclusive one (have a bag lined up under the sink also)
NutriSource Grain Free – I have fed samples with no issue but it is severely overpriced in my area so I’m not sure I would buy a bag to feed it
Taste of the Wild – some don’t like it as it is produced by Diamond and that company had a huge recall issue in 2012 that they handled poorly, but 3 friends feed/have fed it with no issues
Blue Buffalo Wilderness – I have fed with no issues but some owners report tummy and stool issues with their dogs when on Blue food. However, 2 other friends have fed/still feed Blue with no issues.
I am sure others can pitch in with more recommendations, plus, if you can afford it/want to, it really is better to feed canned/dehydrated/homemade/raw. Or you can mix them up – I feed kibble and canned/THK food/fridge add-ins (like eggs, yoghurt, raw bones, etc.). But yeah, just start off with determining what works for Chance, you can always add new things once he is at least on better food. 🙂
