. ... here: Coping with Allergies - Butternut Box GRAINS are not "Common allergens for dogs...", nor are gluten & dairy, nor are [poultry] eggs. // The most-common cluster of food allergens for dogs are proteins, i-e, meats - & that can be any, from rabbit to beef, chicken to goat, whatever an individual dog can't tolerate well. Also, SALT is not an "allergen", it's a mineral, & like humans, dogs require a certain amount of sodium to remain healthy - plus, altho every Butternut Box meal might contain zero ADDED salt, it won't be, & it can't, be "salt-free". Too many things used as ingredients in the food contain salt, in whatever form, already. It might be sodium chloride ['table salt'], potassium chloride, or other salts, but it's already in there, & it's virtually impossible to remove... which is just as well, since most living things require some salts for normal function & even continued life. As just one instance, blood is salty - & every BB box is a meat-based meal. Like Shylock, we cannot get our pound of flesh without the blood within it. Please don't think i'm critical of them - those are just FYI details. I think BB is a wonderful company, & their products sound healthy, clean, & very appetizing, indeed! I read 6 or 8 pages of their website, & heartily applaud the quality of their ingredients, the reuseable / recyclable packaging, their support of homeless & shelter pets, & their carbon-free delivery - that's all fantastic, & i would gladly buy from them if i were a UK resident. I just wanted to point out that 'hypoallergenic' is a tough criterion to meet, & since MEAT is the most-common dietary allergen for dogs, U're unlikely to solve yer dog's allergy issue if U don't already know what s/he reacts to, & ask BB to design an individual diet that excludes their trigger foods [which they can, & i'm sure they will, gladly]. U can't just order something on the premise that "...it's hypoallergenic, & my dog will be itch-free from now on!" I wish U could, but it's not that simple, unless U know what s/he can't eat. - terry .
