7. When you hear the word summer, do you think of ice cream first? Well, your dog needs some delicious refreshing as well! Heres a great way to make your dog happy while being outside: stuff Kong toys with dog-friendly treats, freeze them and give them to your pup! You can stuff Kong toy with whatever treats your dog likes and then put some peanut bitter inside as well. You can basically put anything else thats sticky and gooey, like yogurt and put the Kong in the freezer.
