Creative use of a face mask!

We had the dogs to the vet today.
One of Joe’s eyes has become rather cloudy. The vet had a good look and decided it was not cataracts, more an ageing process and he can still see through it.
For some time now, Lucy has a wart like thing on her head. It doesn’t bother her and it isn’t dangerous.
However, the vet gave us some ointment to put on it. Unfortunately, it seems to attract the flies so we have come up with this solution.
We will only put it on when she is in the garden. She doesn’t like to spend too long there as she was stung there a few years ago.
Could it start a fashion!!
