A baby gate (one of those devices that you fix to a wall and extend across an entrance, such as the entrance to a staircase) goes a long way, anonymous. Additionally, be sure that the floor is kept as clear as possible, never extend cords across a room, and be sure all furniture is fixed to a wall using braces. Likewise, keep all fragile or heavy objects out of your togepi’s reach or equally secured.
While it’s imperative that you do the above first (as not everyone can get a service pokémon for another pokémon), it’s true that service pokémon are available. I would recommend consulting with your Nurse Joy for options and to register for your region’s service pokémon program. Typically, for pokémon with sight impairments, a telepath such as ralts or munna will be assigned to you and your pokémon. The reason for this is that psychic pokémon have the ability to function as another being’s eyes, which is typically a better situation for the battlefield than simply offering a service growlithe or vision augmenting tools.
Best of luck, anonymous!
