i have used wysong for years, yup Ardea! LOL
i like it becouse
They do not change their formulas or play with the ingrediants.
i use the synorgen mainly, cept for my intact animals they are "usually" on the growth.
If i have a male pup who grows exceptionally fast i recommend the bravo raw or omahs pride raw temporarily until they get past the height gaining stage, than it is ok to feed both wysong and raw to.
synorgen is a FABULOUS weight control food for altered animals, including labradors who tend to put on a lot of weight.
my seniors are even on synorgen and do fine thru the whole life stages on this food, without needing a specific senior diet wich i have seen make dogs much hungrier than normal.
