Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to help your older dog navigate slippery floors [title] Cover the slippery area. [step] The easiest way to help your older dog navigate slippery floors is to cover them up. Use area rugs to cover up the area without having to change out the floors or refinish them.

Ending1: [substeps] Move rugs around in a different direction than they are used in the home and move furniture in the opposite direction so the rug stays simple. You can also move small sections to determine the direct seating distance between you and your older dog. Ending2: It is especially important to replace the rugs on slippery floors depending on how slippery your dog might be. If your dog has traction and eventually falls over they won't slip around too much during the first couple of weeks. Ending3: Alternatively, you could place large furniture or rugs across the slippery area to protect the floor from valuable metal shavings. [substeps] Make sure to keep the seating area topped up so your dog doesn't have to sit or tip it backwards when they're walking on slippery floors. Ending4: [substeps] When you place area rugs on slippery floors you need to use a non-slip rug pad between the rug and the floor or you need to get a rug that has a rubberized bottom so that it won't move around. This will help your dog, and you, from slipping and sliding when you step on to the rug.
