I have tried different brands of hot cocoa from dark to milk and the Grove Square milk chocolate k-cups have by far been the best.  They're big critics in my family and they have given two thumbs up.  I would recommend anyone who enjoys hot cocoa to purchase this brand.

Positive

i have just brought one small package of Canidea from my oversea agent 2weeks ago, before my puppy only tried a french brand. First i was just mixed them together and seems ok, but then the old finished there is something weird happened to her, she started eating the stools??!! >:( yes and also vomited white yellowish foam and coughing after totally swished into this brand, even sent her to vet checking blood, taking pills and medical treat which i was thinking she might catch cold. anyway only feel lucky is vet cost much cheaper here... then now she refuse to eat it or only a little if really hungry. most of time she'd rather biting a bone, glad saw the comments here, i will change it to other brand asap :)

Negative
