Bullmastiff

If you live in the city, your urban canine is probably on a three-walk-a-day schedule for exercising, socializing, and eliminating. But if your home comes equipped with a yard and a fence, keeping a dog becomes much easier.

Phydeau can meet his own needs on his own schedule. However, some dog guardians use the yard as a crutch, and, before you know it, the backyard becomes Phydeau's entire world. How much is too much of a good thing?
