Hi Amy, its not the Frontline, frontline only penetrates the first 1-2 layers of their skin, My boy had a reaction to Advantage DO NOT USE the Advantage penetrates thru the skin to their blood, within 24hrs one side of my boys head swelled up his ear & his bottom lip swelled, & he was vomiting blood early hours of the morning, at first I didnt think the Advantage until I rung his vet. the best way to know whats happening is an elimination diet, for 1 month you just feed 1 new protein & say boiled pumkin or rice nothing else no treats nothing, thats if you think it could be foods, I used chicken in Patches elimantion diet but now I think Patch cant have chicken as the lumps on his head that look like hives got worst, Patches vet said that he has seasonal allergies & cause I just rescued him 19 months ago she said I’ll start to see a pattern, I noticed last winter Patch was good, no itch but the end of summer Patch got all his hive like lumps, itching & rubbing along the wall, this winter Patch has his hive like lumps again, so I look in Patches diary & last winter I wasnt feeding him chicken, this winter I was feeding chicken, so Ive stopped the chicken…Ive heard all these test are no good as they give false readings the best would be if you could try him on raw, Im just starting a new kibble called Wellness Simple it has limited ingredients, also watch his carbs, no potatoes, no sweet potatoes, no carrots no high carbs that turn to sugar that makes yeasty itchy skin.. If he can handle it i’d feed raw.. & google a good Raw diet for itchy skin..Ive been thinking of putting Patch on Raw but he has IBD & I have enough trouble trying to find a low fat kibble, so raw would have to much fat for Patch..also there could be a plant or grass in ur garden or on his walks that he’s allergic to, I’ve changed Patches walking route to see if that helps….Its winter here in Australia, so if Patch has enviornment allergies or seasonal allergies like his vet said, why is he getting them now being winter & he didnt last year, thats whats making me look at his food this year, I use Malaseb Medicated shampoo, & I use a cortisone cream when he gets some of the red itchy sores, I found the cortsone 1% cream is excellent Im just using my cream…just look at the ingredients in his kibble & see if there’s Potatos sweet potatos carrots, lentils any high carb foods…A friend from the dog park had a staffy that was so itchy he was red & losing his fur she tried the vet diets they didnt work then she tried the Holistic Select Adult health Anchovys sardines & salmon & her boy is looking excellent not scratching fur all grown back..so a few people from the dog park are using the Holistic Select with great results… Im also given Patch tuna & pumkin for breakfast to replace the chicken & his hives have gone. sorry for the book..Oh a good dog probiotic this will help too…good-luck
