Ysabella,
I can understand your frustration. I work at a Doggy Spa and Boutique and I take Harper, my English bull terrier/ border collie mix, with me to work very often. We have a cookie jar that sits on the counter full of assorted treats- mostly homemade. Harper is allergic to grains and chicken so I have to be very careful of what she gets, even treats. So many people would just toss her a treat if she was out roaming in the boutique, I got to the point where I put a sign on the cookie jar saying to ask before treating, and overall it has worked, if people want to give Harper a treat we have a little stash that are just for her, we use orijen dehydrated treats and she loves them and you can’t get much better than that.
So I would she tell everyone that she does have food allergies, and just put a sign on the jar stating that one of the dogs has allergies and to ask before treating.
Hope this helps, I know it can be hard to deal with eliminating all allergines.
