3/16 Meeting
Design considerations for future would allow wheels to be locked when Bodie tries to drag himself in the sitting position.
Pee pad adjustments to avoid being leak prone.
Ideas for how design can be made adjustable for other paraplegic dogs.
Brought up ideas such as telescoping frames, push button etc. Certain component locations would still require some degree of customization.
