#5: Groom Or Massage Them
Most dogs love being pet — and owners know this is a good way to show them affection. Even more than that, doggies love belly rubs.
Petting your dog always releases oxytocin in both the owner and the dog, which makes them truly feel the love.
In addition to petting them, you can give your dog a loving grooming session or a gentle massage. This will definitely tell your dog you adore them.
