Rather than leave them at home, alone, unattended, they are being offered the option of doggie day care in many cities. The professional association of dog day care providers has a website with its recommendations. Make sure all dogs are supervised continuously. Day care centers should look and smell clean but not have a bleachy odor Staff should have experience in various types of pet care, health and handling. Look for pictures, ribbons, awards, and membership certificates that show involvement in dog activities.
Inexperienced caregivers are the most serious problem a dog day care center can have.
