Thanks for using Petco Pet Education Center, formerly Petcoach! That means that when low, she had a milder reaction to that specific allergen versus the high she had a more significant reaction to that particular allergen meaning that she is more sensitive to it. I hope you found this information helpful. Good luck and have a great day!
