Is the dog really suffering?

Ranger the RescueDog is not suffering. If he were to place a personal ad, it would resemble this:

Single, spunky chocolate lab mix seeks fun loving dog for friendship. If you like to bark at people walking down the street, hunt for treats and eat questionable items, please send me a note. Almost everything is negotiable except total agreement that squirrels, cats and birds are evil and must be stopped. A love of cheese and peanut butter would be helpful but not necessary.
