Our friends have a standard. Unfortunately has cancer now, but still ticking... they love being kept clean, are very smart and need to be exercised. This dog even sick insists on her two walks a day, gets very bored if she doesn't get them.
OH? 2 walks a day???? Wow ----- I thought my dad was doing good with his one hour walk a day.....he's 85 and has arthritis - not sure he can do 2 walks a day....maybe hire a dog walker....or ask a neighbor to do so.
