Hi. I have 2 Australian Shephards both have allergies that start in Fall with vomiting & low appetite then that gets better in winter except for extremely dry skin they scratch til it bleeds. Couple years back they put the oldest one on meds that blew him up so big and its hard to get the weight off. Has anyone found something that works preferably natural? Ive switched food, tried ACV in water, Olive oil in food and nothin works, they are miserable for months. Ilove my Aussies! Thanks you all!
