Allergies suck!

Well, im gonna guess it probably the flaxseed.

here are the ingredients for TOTW Pacific, the highlighted items are common items in both, so the suspects are the ones left over. The ingredients higher on your list are the most suspect.

Salmon, ocean fish meal, sweet potatoes, potatoes, canola oil, salmon meal, smoked salmon, potato fiber, natural flavor, choline chloride, dried chicory root, tomatoes, blueberries, raspberries, yucca schidigera extract, dried fermentation products of Enterococcus faecium, Lactobacillus acidophilus, Lactobacillus casei and Lactobacillus plantarum, dried Trichoderma longibrachiatum fermentation extract, vitamin E supplement, iron proteinate, zinc proteinate, copper proteinate, ferrous sulfate, zinc sulfate, copper sulfate, potassium iodide, thiamine mononitrate (vitamin B1), manganese proteinate, manganous oxide, ascorbic acid, vitamin A supplement, biotin, calcium pantothenate, manganese sulfate, sodium selenite, pyridoxine hydrochloride (vitamin B6), vitamin B12 supplement, riboflavin (vitamin B2), vitamin D supplement, folic acid

So that leaves you with:

Fish broth (unlikely), ground barley, carrots (unlikely) Ground Flaxseed, Salt (unlikely) Carrageenan, Guar Gum and so on.

Welcome to my world.

How much was Joker outside today?  Food allergies rarely exist completely separate from atopic (inhaled) allergies.  Often it's not that they're *just* allergic to food, but food tends to be the easiest to isolate and when the allergy/pollen outside is high, then it takes just a minor thing food-wise to cause a reaction.

It could have been literally anything on the list -- I wouldn't try to play a guessing game with it.  But you may  need to do something to bring the general allergy level down.  Honestly as easily as it could have been something in the food, it could also have been "overload" simply by virtue of one more thing outside "blooming" or a new type of something he sniffed out inside (do you have a finished basement?  wallpaper? etc.)

I"m not saying it wasn't the bit of food on the spoon - but even IF that was the "straw that broke the camel's back" so to speak, it was likely exacerbated by the general flora/fauna outside and it just took that one lick of food to push him over the edge.

 No telling. Like Callie said, a lot of it is contact and inhaled allergies. Emma is allergic to human dander, and several kinds of grass. Honestly? I thought I had her food allergies pretty pinpointed, til I had her allergy tested. We're still working on introducing one food at a time, and it's ridiculous, really, how many things the poor girl is allergic to! It's hard to tell, though, because they're reacting to something else. I have always allowed my dogs to "clean up" my dishes. Well, she's allergic to my dander, so eating my saliva breaks her out. I thought it was a food reaction!

 If it's nice out(not raining) Joker and the others are outside all day. And he only breaks out when I give him something other than his kibble. Takes 30 minutes and he'll be broke out and red. The only things I give him food wise is his kibble,mackeral,fish oil, and peanut butter. Poor boy dont even get treats these days.
