I honestly think giving your dog to a friend / dog Walker is more risky than just taking your dog out yourself.
I know everyone's situation is different and depends where you walk, but for me I'm on a dog walking WhatsApp group, so I told people I'll be staying well away and not coming to say hello, and I just took my dog out staying about 20 metres away from people, i usually let my dog off lead but kept him on so I didnt have to invade peoples space to get him if he went too far.
