I'm a professional house dog sitter,
well that what I like to call myself,

and believe me all animals need/like company, the amount of sad dogs I see during the year is enough to make you cry all they need is food a walk and a cuddle now and again, but most owners miss out the last bit.
I have been told many time by the owners that their dog seems different after a week with me, I don't say anything as I want their money so I keep my trap shut.
As others have said “a dog in not a pet you pat on the head when you come home from work”, sorry.
