We have been very happy with Zignature for over 3 years now. Our oldest pug Casey, used to have horrible problems with allergies, those stopped when we switched to Zignature! His 5 year old pug brother Oliver is doing wonderfully worth Zignature too! I have been reading everything and listening to your research and responses and we will continue with Zignature, I’ve found no real data that would tell me to do otherwise and we are happy and healthy on it! Please continue your great work for our furbabies!
