All the petsmart and petco's in my area are out of stock on most of the Avoderm food bags.. I have Louie on Salmon and potato formula and those are out of stock everywhere i've gone.. i'm familiar with petflow just that the nearest petsmart is little less than a mile so i dont really have to go out of my way to get his food until now.. you guys have any suggestions what i should do for the mean time..? his food is almost out and i'm not sure if i should switch his food over night or give him a different formula of Avoderm.. i know for a fact he's allergic to the chicken and brown rice puppy formula but the rest are for adult or senior dogs.. would it be fine if i give him adult avoderm? i think it's beef flavored or so.. he is 5 months by the way.. thanks!
