A pet day care center or spa should offer a good staff to pet ratio. While the pet will be kenneled some of the time, they should also have lots of interaction from people at the center, after all that is the reason you don't want they staying alone at home. Ask the time the pet will be alone and the time they will be with a staff member.
Your dog's diet should be one of the first and more important dog care needs you have. But, do not be fooled into believing that those very expensive products are the best for you. Instead, look at the label. Protein should be one of the first things listed there. While inexpensive food care products are not the best either, look for a middle ground.
