Take pictures with your dogs, not just of your dogs.
You never know when something will happen. And when you look back, you will want pictures of you together.
You might not like how you look- your hair is messy, you want to lose some weight, you aren't wearing the best clothes, you don't like your smile, or whatever it is. You might just hate getting your picture taken. But get over it, and take pictures with your dog.
I had just finished a two hour hike with lots of elevation gain when we took these photos. My jeans are stained on the knees, I'm wearing just another t-shirt, my hair is in a messy ponytail, etc. Pick it apart all you want. But even though I don't really like posing for photos, I made a point of asking my mom to take my camera and get some photos of me with my dogs. Because a friend of mine lost one of her dogs last week and will be forever grateful for the photos her husband took of her with her dog before he was put down.
So take pictures with your dogs. You might not get a do over.
