My morkie has to have his food warmed and his water chilled - he drinks bottled (no special brand). He was 'kicked out' of Camp Bow Wow for 'nipping' (he just wanted to play), then ran away from the Pet Nanny, so now he is Home Alone and a Pet Sitter comes over 3 times a day to feed, and play with him while we are gone. He is much happier.
