Prepare for unexpected vet bills
If you already have one or want to make your shopping trip more worthwhile in the long run, considering getting your dog an interactive toy or puzzle. They're great for keeping even the antsiest of dogs mentally entertained and they're certainly fun to watch for owners too!
If you have a particularly hyper dog and can't get outside or to an indoor park like mentioned above, consider making your dog an indoor track or exercise area. Staircases and treats are a great way to get your dog moving and tire them out, but with a little creativity, there are tons of ways to get them panting indoors.
