I am glad that your brought up this topic. Currently we have funding to look into canine allergies, and have included a survey that gets at this topic. It is something that is impacting many dogs and we hope to help through this research!
As for the kits, yes we are still backlogged. We are a small group and doing our best to get them out to all eligible participants. Sending out kits to thousands of participants is the responsibility of really 1-2 people and it is a lot of work. We ask for your patience as we are doing our best. Thank you! 🙂
