AlwaysSmiling, I’d never used, or would have wanted to use a dog Walker. I’ve always had dogs, often 2 or 3. Never any problems.
Almost 2 years ago, my husband was unexpectedly given a dreadful diagnosis. He lived for 6 months during which time we had alternate weeks of 3 days a week hospital, following week recovering. Our lab was 16 months - a huge, powerful , giddy, teenager. I found a well recommended dog Walker. It was a disaster as she was dishonest and mixed him with large groups of unstable dogs, off lead rather than the 3 other dogs she’d said.
This is one of the reasons my earlier post made suggestions to Fanny.
When our lab joined us (and our older dog) we were well able to walk miles. Life gets in the way sometimes and plans have to change.
