15 year old addition! Advice please :)

We just adopted this 15-year-old lady! She’s been absolutely wonderful. She’s very active for her age, but we do realize she’s old. We are looking for a backpack we could put her in when she doesn’t want to walk anymore. Any advice? We are also looking for the best Food/water bowl situation. Our two other dogs have a neater feeder that’s raised up so they don’t have to bend down so far. Wondering if there are similar ones for Bassetts! Thank you!
