Dog tired during medication delivery

I was tasked to deliver medication to a shielding woman in Hampstead. I decided to walk the dog to the chemist and then to the ladies home nearby. She had been shielding since March! So was very pleased to have a chat and receive her medication. ( she lives very near the Hampstead ponds with all the ducks much to the interest of Gus) Gus was very tired especially as we added some litter picking to our afternoon out.
