MetalSmitten said:i'd personally try the venison&potato if it's available (and i do believe petco carries it now) - the duck can be a little rich for some dogs and takes them longer to adjust to. the duck is also good though as long as you transition them slowly i think they also have a lamb&rice version but either of those could possibly be a trigger if she's had them before, so i'd probably avoid that at first.
actually, i just visited their website, and it looks like they also have a new bison&sweet potato food, which also looks good really, of those three, pick whichever you think your dog will eat but hasn't eaten before, and you should be good for starting an elimination diet test. if you don't go with natural balance, just make sure you read the ingredients lists, most foods have a main flavor that they'll say on the front of the bag, but multiple ingredients listed on the back.
foot chewing is another classic sign of an allergy, often food, sometimes environmental. i would usually see the trifecta of ears, eyes and feet when dealing with food problems. also dandruff can be another symptom of food issues. when you switched her food last time and it seemed to help, did that happen to be right around the same time as any environmental changes? or was the environment pretty steady during that time? We got her last March from the humane society. Took her to the kennel for the first time about June, so probably switched her food about July. So a year on the Fromm's. We were still trying her outside last year, but the way the bugs attack her, we couldn't do it, and I'm home during the day, so she gets to be spoiled and be a house dog. Seasonal allergies were crazy around here last year. We're not quite as high for cumulative pollen count this year, but it's still a really high year. She did seem better in the winter and during the spring. Like I said, she's never not scratched, but it got to the point where it was only a little and her ears healed up, so we figured she's kind of mental. The last two weeks, she's back to being horrible with constant scratching to the point of scratching it raw on the outside of her ear and chewing her feet. I guess I'll have to see if Petco carries the bison and sweet potato, because the Fromm's has duck, potato, rice, chicken in it, so those flavors wouldn't be eliminating anything. That's why I was suspecting "seasonal" allergies, because she's gotten away from us a few times in the last couple of weeks (love my 2 yo grrrrr) and run through places that she hasn't been in for months, like through the corn field, through the swampy pond, and down to the farmer's at the end of the road. Hmmmm - she did run through the cornfield within a couple of days of them spraying it, wonder if that might have triggered something, but she did get a bath that night when I got her home, since she decided to roll in the cow yard..i suspect food intolerances because you mentioned switching her diet helped before, but it could be environment if it's seasonal to specific times of year. or it could be both. i've met dogs who were literally allergic to grass, smoke, cats, other dogs, and even to people.
if she's okay with dairy, you could plop some plain yogurt on her food too, to get some probiotics in there.
