Hi Shannon, food change is good place to start & weekly baths, it’s not rare for dogs to have food sensitivities & become real itchy or have smelly ears & skin, rub bum on floor, it’s rare for dogs to have “food allergies” & when a dog does suffer with food allergies they normally have IBS symptoms & Skin Problems….
Have a look at “Canidae Pure” formulas, most formulas have single proteins with only 5 to 7 ingredients & grain free, Canidae Pure Sea is a really good formula for itchy dogs, the omega 3 is nice & high, what’s need for itchy dogs, Canidae have just brought out their small Pure Petite formulas, they’re lower in fat & lower in protein then their other Pure formulas, have a look at the Petite Pure Salmon formula for your itchy dog or Pure Sea & the Pure Meadow Senior for the 2 older dogs or they can all eat the same formulas just don’t feed a new kibble that has the same protein what they are eating in the Blue Buffalo formula, try & change ingredients…
also start weekly baths, I have found Malaseb medicated shampoo to work the best, Malaseb can be used daily to wash off any bacteria, allergens, pollens & dirt off their coats & skin, relieving their itch & killing any bacteria on the skin, I bath weekly thru Spring & Summer months & as Winter approaches I bath fortnightly, Patch suffers with Seasonal Environment Allergies & Food Sensitivities….
Once you change diet, give no treats, unless the treats are the same brand as kibble & have same ingredients as the kibble, Canidae has matching treats & wet in food & diet is higher in omega 3 fatty acids & you start bathing twice a week, you’ll start to see a big improvement with the itchy dog, keep….
There’s no true testing for food sensitivities or food allergies, the best thing to do is a elimination food diet or feed a vet diet or a novel protein, limited ingredient kibble like Canidae, then once dog is stable & isn’t itching or smells real yeasty like a corn chip then you can start adding 1 new food to diet for 6 weeks, it can take from 1 day to 6 weeks to show any signs of a reaction to a food…..
Keep a diary, my boy starts getting itchy ears & shaking his head after eating carrot, red front paws & real smelly yeasty skin from chicken, barley, rice & oats…then in Spring he becomes real itchy from seasonal environment allergies, which ones I don’t know but there’s a skin test called “Intradermal Skin Test” where they shave a part of the skin normally the side of the dog, then they inject just under the skin the most common allergen & see if the dogs skin reacts, humans also have this test, then once they work out what in the environment your dog is sensitive too you give injections to desensitize your dog from what ever is making him/her itch.. that’s why it’s best to keep a diary & you’ll start to see a pattern, what month they itch more, was it after eating a certain food, or when Spring came, or on real windy days when the pollen count is high etc
Another good kibble brand people are feeding is “Zignature” but just check the fat & protein % in the kibble your feeding at the moment, the Canidae Pure Petite may be more closer fat protein & fiber & be around the same % to the Blue Buffalo….Zignature Kangaroo has the lowest fat, protein & fiber the other Zignature formula are higher in fat protein & fiber & might cause stomach/bowel stress especially the older 2 dogs… Your dogs may be OK when they change formulas, make sure you introduce over 7-10 day period, a lot of people do it tooo quickly then blame the new kibble when their dog has intestinal stress…
There’s a really good group on Face Book called “Dog issues, allergies and other information support group” a Dermatologist is in the group, Dr Karen Helton Rhodes DMV DACVC, after changing kibble & giving weekly baths in Malaseb shampoo & there’s no improvement with the itchy skin I’d join the F/B allergy group your dog may be allergic to dust mites or storage mites found in food or something in the environment, there’s a lot of new things on the market like Apoquel & CADI injections…
