Dogs are your pet, your friend, your child, buddy, playmate, and emotional support. My best friend was Shotgun––a corge/aussie shepherd mut that my dad picked up outside the pound he worked next to. We named her Shotgun because she always insisted in sitting the passenger seat of our car. We grew up together and did everything together. She was great in every way possible...so long as she was the only dog in the house. 3 years ago she was 16 and we had to put her down because she couldn't get up anymore. Saddest day of my life. In 3 years we have adopted, bought, or fostered for 3 other dogs. All of them sucked for some reason or another (previously abused/injured and never warmed up to us). 3 years and I still miss her. 3 years and no other dog compares.
Go hug your friend. Be nice to them. Even when they do something stupid just remember they probably didn't do it to piss you off. Make sure to give them the attention they deserve. Even when you get super busy, put some time away for them.
Picture related, it's what I was doing 5 minutes ago.
