Hi all. Bonnie is itchy. Sratching and biting at herself. I took her collar off, 'cause she sratched non stop with it on. I have very carefully looked at her skin and tummy areas. NO fleas. No flaking. No redness. She is an extremely active little thing, goes, goes, goes, sleeps! I am slowly changing her food to a 5 star kibble. Maybe that will help. She has one more treatment for giardia tonight, then she's done. Any ideas.?
