You can prevent indoor accidents by knowing when your dog needs to pee or poop. Circling, sniffing the floor and walking up and down are sure signs that your pooch needs to go! Always react and offer lots of praise afterwards too.
Dogs (and some cats) like cool treats just as kids do. Consider freezing Ultramix sweet potato or pumpkin puree dietary supplements in an ice tray and serve ice as a summer treat. Alternatively, turn the frozen treat into something special by freezing the mixture in small plastic cups and using a natural chewy treat as the stick. Insert the treat when the puree is partly frozen to get the stick to stand up properly. The treat should be easy to remove from the cup if you run the cup briefly under lukewarm water.
