Hi Christine,
What symptoms does your dog suffer with?? IBS stomach/bowel symptoms or just has skin allergies??
He might have Seasonal Environment Allergies, now he’s doing better cause it’s Winter & plant/trees in your yard or neighbouring yards aren’t flowering etc
You will know when Spring & Summer come back around keep a diary..
Or he was sensitive to ingredient in the grain free food, my boy can NOT eat a G/F kibble that has Tapioca, he starts to smell yeasty, scratches, itchy, scratches bum on carpet, Lentils cause bad gas, wind pain then has diarrhea, when he eats Barley he gets yeasty smelly skin, yeasty paws & sloppy yellow poos, rubs bum on ground, Corn Gluten causes yeasty smelly skin, paws, sloppy poos then diarrhea & rubs bum on ground, Oats = yeasty skin, paws & sloppy yellow poos, rubs bum on ground, Carrot cause itchy ears, shaking his head/ears..He doesn’t do well on any grain formula’s..

When he eats a grain free dry kibble that has Potato, Sweet Potatoes, Chickpeas further down the ingredient list his IBD & skin goes really well thru the Winter months then when Summer comes around something in the environment causes bad skin allergies, I know grass & wet grass is 1 allergens he suffer from, he goes down hill with itchy skin, red paws, whinging & he’s eating 1 of the same G/F foods he did well on thru Winter months, I rotate his G/F foods, Wellness Core, Wellness Simple Turkey & Potato & Canidae Pure Meadow Senior & Canidae Pure Wild Boar all Grain Free formula’s.

If a dogs diet has too much Omega-6 & is way too low in omega-3, the omegas need to be balanced properly then the dog will suffer with skin problems…
eg-Omega-6 Fatty Acids-2.80% Omega-3 fatty Acids-1.00%,
Omegs-3 should be nilly 1/2 of what the Omega-6% is…

Pet foods that are AAFCO aproved means nothing as some are NOT balanced properly… this is 1 thing Susan Thrixon pointed out in her recent link

DCM Study Misses the Big Picture

If he’s doing well on Blue Buffalo feed it but I would also rotate & feed another brand that has similair ingredients as the Blue Buffalo he does well on has. This way if there is something wrong with a certain batch, or its not balance properly etc he isnt eating the same dry dog food 24/7 also if ever something happens you know of another brand you can fall back onto..
