I view dogs as part of the family and treat them that way. I give them love and rubs and whatever they prefer as all animals prefer different treatments. I walk them as they like, feed them on their schedule and play with them often. I have lived with and loved rescue dogs for most of my life. I've had a few purchased dogs when I couldn't resist. I would communicate if there were any issues going on right away. I have had a couple cats and kittens over the years too. I would respect the owners wishes if they had specific requirements for their dogs care and treatment. I would not start any bad habits with their furry family member. I would only treat as requested.
